Frequently Asked Questions

There's a certain magic in the act of collecting a freshly laid egg from your backyard coop—a tangible connection to the rhythms of nature and the reward of your nurturing efforts. But have you ever paused to consider the intricate journey that transforms a simple yolk into a fully formed egg? How Long Does it take to Lay an Egg? This whole process of egg laying from yolk to coop takes around 26 hours. As you savor the flavors of a meal made with your own homegrown eggs, take a moment to reflect on the incredible journey behind each bite. The...

The brown color in an egg is laid on in the chicken's reproductive tract by the shell gland pouch. Some breeds lay a tinted egg with a very light brown color, while others lay extremely dark chocolate brown eggs. From right to left: Marans egg, Welsummer egg, Rhode Island Red egg. Within a breed, too, hens can lay eggs darker or lighter than the average, depending on whether they produce more or less of the brown color that goes on the shell--and how long the egg stays in the "paint station" of the reproductive tract. Interestingly, individual hens--while they lay...

We like them all, Sam-I-Am! No, there is no difference in terms of edibility, health, or nutrition in different-colored egg shells.  That said, the colorful eggs from your backyard hens WILL have much more nutrition, because eggs produced by hens raised on pasture are much healthier, indeed (and they taste much better, too). Keep in mind that commercially produced "free range" eggs may have been laid by hens who have never seen a blade of grass, the sun or the sky. "Pasture-raised" is something different, and much healthier. Eggs laid by hens raised on pasture have less fat and cholesterol,...

There is no reliable way for the average home hatcher to tell the difference between an egg that will hatch a female chick and an egg that will hatch a male chick. In-ovo DNA testing and spectroscopy are being developed for certain applications, but most of us don't have this technology readily available at home! Instead, there are lots of old wives' tales out there, most of which have to do with the shape of the egg or which way a string swings when you hold it above an egg. In most cases, you will find that in one area...

Fertilized eggs are fine to eat, in fact some people claim they healthier than unfertilized eggs, although we've never seen any data supporting that. (Let's be honest; if the fertile egg is fresh and unincubated, you're going to have the addition of just half a cell.) Illustration by Ray Yang for My Pet Chicken It is impossible to taste the difference between a fertile and an infertile egg, and barely possible to SEE the difference between a fertilized and non-fertilized egg with the naked eye. If you look closely--and if you have good vision--you will see that a fertile egg...

Whereas the brown color of an egg is laid on the outside of the shell, the blue color actually goes all the way through the shell, even to the inside of the shell. Originally, it was thought that color pigments were synthesized in the blood by the breakdown of hemoglobin, but research shows it is more likely that they are actually synthesized in the shell gland pouch. The blue color is produced by biliverdin; the brown color is produced by protoporphyrin, and they are incorporated into the shell in different ways based on their different compositions. Again, to make it...

Yes, they can! There are no problems associated with hatching mixed breed chickens. If you have a rooster in your flock, he will try to breed ALL your hens, nevermind if he is a different breed or even if the hens are different sizes, bantam and large fowl. It can be fun to hatch "mixed" eggs, because you never know what you'll get! Actually, many of the breeds we offer at My Pet Chicken are designer cross-breeds, and the results are spectacular: wonderful plumage colors, fantastic new egg colors, prolific egg-laying, friendly personalities and ultra-hardiness. For instance, we loved our...

It's counter-intuitive but true: Your eggs will stay fresher if you don't wash them at all. When your hens lay eggs, there is a natural coating that is laid on top called the "bloom" that helps keep out bacteria. When you wash eggs, you can drive some bacteria in through the pores of the shell, so it's a bad idea to do so unless needed just before cooking as a general practice. If your nests are clean, your eggs should be clean. In fact, fresh eggs don't really even need to be refrigerated if they're going to be used soon....

My Pet Chicken absolutely guarantees that the fertile hatching eggs you order from us will arrive intact and ready for incubation. Hatching egg orders may ship any day of your selected shipping week, Monday through Saturday via USPS Priority Mail. If any eggs for which you have paid arrive cracked or broken, contact us within two business days of receiving them with photos of the damage. - IMPORTANT: Receiving unbroken eggs is NOT a guarantee that they will all hatch. Why? Let us tell you BEFORE you make your purchase so you can be informed. Our eggs are gathered daily and stored...

Cloudy whites in a farm egg are usually indicative of its freshness. The cloudiness is caused by dissolved carbon dioxide in the white, which eventually escapes through the shell in older eggs. If the white of the egg is greenish, that usually means there is too much riboflavin in the diet. Make sure they are getting balanced nutrition. Eating acorns, shepherds purse or some types of weeds can cause that greenish tinge, too. Pinkish whites are caused by some types of weeds a chicken may get into, or high quantities of cottonseed meal in the diet.

Usually the whites of very fresh eggs such as you may gather from your own flock will be very thick in comparison to what you may be used to seeing at the grocery store! However, watery whites can be caused by a number of things. Eggs that are old will have watery whites (this is usually why grocery store eggs are so thin and tasteless). High ammonia levels in the coop can cause watery whites, too, as can high temperatures. These are other reasons factory farmed eggs are usually not very good: the conditions chickens experience in places like that...

A shell-less egg is a strange sight! You might think a shell-less egg would look like a cracked egg: a mess of white and yolk soaking into nesting material. But actually, an egg without a shell is often intact. Even an egg without a shell has that soft membrane. You might even think it's a regular egg until you touch it! Chickens need a lot of calcium to create good, hard shells, so most incidences of shell-less eggs in an adult hens are related to not having enough calcium in the diet. Young hens may lay a shell-less egg or...

These spots aren't related to having a rooster--or not!--in your flock. Presuming they are fertile, eggs with blood or meat spots are actually less likely to hatch. They don't mean your hen is sick, either. Blood spots usually just mean there has been a small rupture of a tiny blood vessel during egg formation, and this can happen even in healthy hens. They can also be triggered by too little vitamin A in your hens' diet. Occasionally, you may see a meat spot, which happens when there is a rupture along the wall of the oviduct. Both types are harmless....

You may be describing what is called a "body checked egg." Body checks are ridges or grooves that occur around an egg, usually at the pointed end. They occur more often in older layers, and are not really a cause for concern to the backyard farmer. Commercially, they are considered a aesthetic flaw, but don't have any effect on edibility. Occasionally, the egg will even appear wrinkled all over or even misshapen due to a large number of checks. Body checks are usually result of the hen's body attempting to repair any eggshell damage caused by stress when the egg...

This is usually an occasional thing, although younger or older hens are more prone to it. If your chicken is young, sometimes rough shells can occur for a while until her egg-laying cycle has settled. Older chickens may lay eggs with rough or pimpled shells, too. This issue can appear at any age, however. For instance, in the winter, sometimes a chicken may be getting excess calcium as laying slows down and they are less able to graze; the excess is distributed over the shell, sometimes in "pimples" or rough patches. Other possible causes: sometimes, rough shells will be caused...

The question of temperature-dependent sex determination (TSD) in chickens has been an important subject for scientific study over the last several decades. For most backyard chicken enthusiasts, females are preferred for egg laying and unwanted roosters often have to be rehomed. Wouldn't it be great if you could incubate and hatch all females, or at least hatch a much higher ratio of females than males? Sure! But as we shall see--don't get your hopes up just yet... An Australian study published in 1960 (Australian Journal of Agricultural Research 11(4) 664 - 672) found that eggs stored at 40 degrees Fahrenheit...

Awww, isn't that cute! Tiny, yolkless eggs are sometimes known as witch eggs or fairy eggs. Cute, huh? Occasionally a hen will lay a fairy egg when something has disturbed her reproductive cycle. Sometimes a hen will lay a fairy egg or two just as she comes into laying, before her reproductive system has gotten into gear. They do come in all the colors that hens lay: white, brown, green, blue and so on, although they are sometimes lighter or darker than her regular eggs because they may spend more or less time in the "egg painting" area of her...

Bantam eggs in general are quite small by comparison to what you see in the grocery store. That makes sense! Smaller birds lay smaller eggs. Below you see two cochins, one a bantam and the other a regular-sized large fowl cochin. Of course the bantam cochins will lay smaller eggs. (They have smaller chicks, too!) Regardless, bantam chicken eggs taste the same as the eggs of larger chickens, and certainly if your birds have access to pasture, bantam or large fowl, the eggs will taste MUCH better than what you can get in a grocery store. However, some bantams lay...

The eggs of bantam chickens are smaller than the eggs we're used to seeing in the grocery store. Just how small? Of course, it really depends on the hen. For instance, the eggs of Sebright bantams and Belgian bantams, are SUPER tiny, but the eggs of Silkie bantams are simply small. So all bantam eggs are not equivalent, the same way some large fowl breeds lay jumbo eggs, while others lay medium eggs. Here are the size classifications for eggs: 1 jumbo egg - 2.50 ounces 1 extra-large egg - 2.25 ounces 1 large egg - 2 ounces 1 medium...

Storing your eggs large end up will keep them freshest. This is because the air cell in an egg is located at the large end, so less moisture will evaporate out of the egg if it is set with the air cell up in the carton. The pointy end, with egg white closer to the porous surface of the shell, is less exposed to air when it is pointing DOWN in the carton. Frankly, though, if you are storing eggs for eating, it probably won't make much difference unless you are storing them for very long periods of time (and...

It's not a common problem, but it is an area of concern. Common sense will tell you not to keep your chickens around peeling or flaking paint, lead based or not. But while you can probably identify if you have paint chips falling into an area your chickens frequent, you may not be aware of any contamination that is not visual--- and that's the danger. For example, if you live in an area of old homes that may have used (once common) lead-based paint on siding, trim, barns or other outbuildings, the lead from old paint chips may have turned...

Of course, we can't know for sure what may be going on, but we can offer some information that may assist you in figuring it out! First of all, it's important to understand what it is that causes egg yolks to stay centered in the first place. The chalazae are the parts of the egg that are sort of like springs, and they act to hold the yolk in place. The chalazae are the think whitish parts you will have seen on either side of the yolk. Sometimes people will choose to remove this part of the egg when cooking,...

No, a terrible hatch doesn't mean that most or even any of your eggs were infertile! They may all have been fertile. Remember, just because an egg doesn't hatch (or even if it doesn't develop), that doesn't mean it wasn't fertile. It is not possible to see the fertilized blastodisc, or blastoderm, on the yolk of the egg after 21 days of incubation, as it will have deteriorated by then. �If you have a rooster with your hens, you can presume good fertility up to about a ratio of ten or twelve hens to every rooster. To check your exact...

When a hen has just begin laying, there can occasionally be a little blood on the egg shell, but it is usually no cause for concern. Eventually her vent gets used to stretching when she lays, and becomes very elastic. However, at first it does occasionally happen that with a large egg she might bleed just a little. And it can happen, too, to an older hen if she lays an egg larger than she is used to. If there is a lot of blood, if there is blood every single day, or if you see blood on your hen's...

You will want to gather eggs every day, and refrigerate them as soon as they've been gathered. This keeps them freshest. However, in the "good old days," of course, eggs were not refrigerated right away. That's surprising to many people! After all, milk that is not refrigerated will go bad, and it will do so pretty immediately... but not eggs. In fact, when a hen is laying eggs to hatch, it can take her about two weeks to gather a clutch large enough to incubate. At the end of that time, the first egg is still fresh enough to develop...

There is no one special breed that lays double yolkers. Occasionally a hen may lay a double yolker when her ovaries release two yolks at once, rather than one at a time. This tends to happen more often when hens are young and have just begun laying. Any breed can lay a double yolked egg, but it may be more common from breeds that are good layers, like Rhode Island Reds, Sussex, and Leghorns. Double yolkers are a favorite for over easy eggs! Commercially, most double yolkers will be discarded as "irregular" when candling, so getting farm fresh eggs from...

No. If you want to purchase live birds or fertile eggs, you will need to find a local supplier to help you; we do not ship internationally. (We don't even ship non-live items internationally.) If there is no local supplier and you want to go to the effort of importing chickens or fertile eggs into your country, you should be aware that it's not an easy process. Plus, we still can't help you--we don't export or ship internationally. We get asked often enough that we can provide some advice, though. First, you will need to check to see what customs...

Eggs from your own hens normally have very "tall" yolks because they can be so very fresh! It's not because they are pasture raised, though. The nutritional content for your own eggs when your hens have access to pasture is much better than regular "grocery store eggs." You can visually observe the difference between eggs from hens raised on pasture and eggs from factory farmed birds, because pasture raised birds will have yolks that are dark and orange, as opposed to the sickly pale yellow of grocery store eggs. Notice that in the photo above? That's the natural color of...

It is not likely that the problem is overfeeding. We recommend feeding free choice and not limiting their feed: underfeeding usually causes more problems than offering extra. It is rare for a layer to overeat ("meat" birds like the sickly Cornish Rock crosses are different, and often overeat). If it really concerns you, you might cease fatty treats, or perhaps double check the protein level in your food. Around 16% protein or so is good for layers, so if your protein level is higher than that, you might switch to a slightly lower protein feed. For the most part, though,...

There is no special size that is best across all breeds. Think about it: some breeds lay very large eggs because the chicks are comparatively large; some bantam breeds may have tiny eggs, and the chicks that hatch from those eggs are tiny. Hens of vastly different sizes lay different sizes of eggs. In fact, there are some large fowl breeds that lay small eggs, too... so the size of the egg you want to use for hatching depends on the breed. If that's the case, how do you know which fertile eggs are best to hatch? Choose eggs that...

If you're losing a lot of egg white when you try to peel hard-boiled eggs, the problem is not related to the breed you have, so choose your favorite! What causes the difficulty peeling is the freshness of your eggs, believe it or not. Fresh eggs are difficult to peel, and the eggs you are getting at home now are very fresh indeed. The problem--if having fresh eggs can be regarded as a problem!--is that what peels easily are old eggs. The eggs you were getting at the grocery store were very old, sometimes a month or more old. As...

Of course we can't know for sure what may be causing the problem in your case, but we can try to mention a few things that might typically cause problems maintaining a steady temperature in the styrofoam incubators. First, if you are reliant on manual turning, opening the incubator to turn your eggs does drop the temperature... but that is pretty temporary and shouldn't cause problems if you are quick. It can help to mark one side of the egg so you can see which have been turned and which haven't. (Use something like soft pencil, that won't soak into...

I'm afraid it's not possible to stop incubation, ship the eggs, and then restart incubation afterwards. The chicks would die. It would be akin to a human woman deciding she wanted to take a break from pregnancy for a while to get a nice night's sleep, and asking to have the baby removed for a day or two. Although I think most women would like having the option, especially during the last trimester--I sure would have!--it's just not possible to stop gestation for the fetus--or incubation for the embryo--for a few days without killing it. Make sense? A hen's incubation...

"Red Stars" are hybrid birds; the rooster is one breed while the hen is another. Because of the genetics of the two breeds, the Red Star chicks are "sex linked," meaning that the color of their down when they hatch is linked to whether the bird is male or female. This means that males hatch out a different color from the females, so they are easy to tell apart. Generally you buy Red Star chicks when you want to be assured of getting all females---they aren't vent sexed like other chicks, so vent sexing errors won't occur. Ordering sex linked...

If this is the only symptom you're seeing, she's probably not sick. (If she does show other signs of illness you will want to take her to a licensed avian veterinarian for a firm diagnosis and treatment options.) Interestingly, in some hens that lay brown eggs, eating too much canola or rapeseed meal can cause a fishy smell in the eggs . Not all hens are affected by the process that causes the smell. The smell is caused by the accumulation of trimethylamine (TMA) in the yolk. Most hens metabolize the TMA into another (odorless) compound, but brown egg layers...

This is one of those questions where it's hard to tell what exactly you're asking, a question that tells us you're probably a beginner at incubation. Remember, fertility rates are different than hatching rates. Even when the eggs you place in your incubator are 100% fertile, you may get zero of them to hatch. This is because if the conditions aren't just right---if your incubator is too hot or too cold (or too humid or not humid enough, etc.)---the eggs may not hatch in those sub-optimal conditions. So, hatching rates are dependent on YOU, and how well you or your...

In almost every case, starting a laying flock with baby chicks will be easier and less expensive than starting one by hatching fertile eggs at home. Don't get us wrong, home hatching is great! But remember that fertile eggs (supplied from any source) are not guaranteed to hatch, because shipping can be so rough on the eggs. With shipped eggs, the average hatch rate is about 50%. That's just the average, though! That means sometimes you will have higher, and sometimes lower. In fact, with eggs, it is possible to do everything right and still not have any hatch. Plus,...

Well, we can tell you HOW the different colors are made, but as to WHY the different colors are produced, there are just theories. There are guesses, but no one really knows for sure. It's intuitive to think that the colors and patterns of bird eggs should help provide camouflage for the eggs while they're in the nest. However, it's been problematic to show a relationship. For instance, one scientist, Gotmark, painted eggs different colors (brown, white, blue, spotted) and placed them in nests with varying degrees of cover, then kept track of which eggs suffered predation. The color didn't...

Generally speaking you will NOT want to intervene in the hatching process when incubating fertile eggs. If conditions in the incubator are right, it can take 24 hours for a chick to escape the egg after it has pipped, and that's perfectly natural and not a cause for concern. Often it takes much less time, but 24 hours or so is fairly common, too. If it's been more than 24 hours since the chick first pipped and you have had problems maintaining a high enough humidity during incubation, the problem may be simply that the chick is stuck to the...

Wouldn't it be nice if you could get such good eggs in the grocery store? Until things change, though, most people really can't. Studies show that eggs laid by hens raised on pasture--in other words, hens who have access to a yard or run where they can forage--have less fat and cholesterol, and more healthy vitamin A, vitamin E, beta carotene and omega-3s. A follow-up study confirms the findings, and shows additionally that pastured hens also lay eggs with increased vitamin D--three to six times more! By contrast, eggs you get in the grocery store are typically laid by hens...

A lash egg is less of an egg than it is a roughly egg- or sausage-shaped exudate, consisting of thickened pus and other materials. It is probably the grossest egg your hen will ever lay, and will often look like cheesy, bloody strata or other matter arranged in strappy, skin-like layers. You may think she's expelled an internal organ. Ew. Seriously.  If your hen lays a lash egg, it means she is sick with salpingitis, which is an infection of the oviduct. Please take her to a veterinarian immediately.

If your hen lays a lash egg (something you won't soon forget--they're pretty gross!), you can be pretty sure that she has Salpingitis, meaning her oviduct is infected. This is really bad news for your hen and may be fatal, and she could continue to be a carrier even if she recovers! Read more to find out more about this disease: Salpingitis Also called Inflammation of the oviduct, infection of the oviduct Prevalence Common Signs General signs: No or mild signs in adult birds, including lethargy, loss of appetite, drop in laying, yellow poo, wheezing, coughing, sneezing, discharge from nares...

There are a number of possible reasons your chickens are not laying eggs. Let's look at a brief overview of reasons to give you some ideas, and you can click on each possibility for more details and a more in-depth discussion. Reasons your chickens are not laying Your hens may not be laying because they are too young. Your hens may not be laying because they are very old. Your hens may not be laying because it's wintertime. Your hens may not be laying because they're molting feathers. Your hens may not be laying because they're broody. Your hens may...

Exactly 157. (Just kidding!) Actually, how many eggs a chicken lays a year depends on a lot of things, but especially on the breed of your chicken and her age. For instance, young Leghorns may lay 300 eggs per year. Young Cochins may lay only 100 or so. Sumatras may lay 50 or fewer. By breed, you can see a general idea of how many eggs chickens may lay per week here on My Pet Chicken's chicken breed list. But keep in mind that as the birds get older, they will lay fewer eggs. And some breeds are not great...

Assuming that they have had proper care, lighter-weight duck breeds mature sexually at 17-24 weeks of age and begin laying eggs at that time. Heavier duck breeds usually start laying between 20-30 weeks of age. However, if they reach maturity during winter--just like chickens--ducks may delay laying until the days begin to lengthen and it warms up in the spring. Just before and during production, ducks may exhibit swollen abdomens, large, moist vents, and widely-spread pubic bones. In some breeds, you may see a darkening in feather color, and in others, the bill color may lighten. Normally, geese start laying...

Hatching eggs at school can be a rewarding and enlightening school project! In fact, the founder of My Pet Chicken was first charmed by chickens during a hatching project in grade school. After that project, she was a changed person! In her eight-year-old heart, she knew for a fact that she would keep chickens herself and help others adopt chickens when she grew up. And now, years later, you can see from our website how that turned out! So, at My Pet Chicken, we have a definite soft spot for schools who want to organize hatching projects. That said, though,...
