A chicken lays an unfertilized egg because the egg is already mostly developed even without it being fertilized and because it's the chicken's natural biological process to produce unfertilized eggs to lay even when they are not fertilized.

Hens do not need a rooster in order to create and lay eggs.

All they need is a safe place, time, and a healthy diet with enough protein and calcium to form healthy eggs.

Of course, any eggs laid by a hen where no rooster is present are going to be unfertilized, and therefore will never hatch.

A male chicken fertilizes an egg with his sperm by jumping on the hens back and lowering his tail and then touching the hens cloaca with his cloaca.

If the female chicken does not have any contact with a rooster or male chicken then the eggs are not fertilized and will not hatch.

Grocery store eggs cannot hatch into a chick as the eggs in grocery stores are not fertilized.

For a chicken egg to hatch into a chick it must be fertilized and because the male chickens and female chickens are separated at around a day old in commercial egg production the grocery store eggs cannot become fertile.

The part of the egg that turns into a chick is the white spot on the yolk that is called the egg cell or germinal disc which is where the baby chick develops from.

The yolk of the egg provides the baby chick with food while it's growing in the shell.

The white part of an egg is not chicken sperm or even a beginning embryo but instead the white part of an egg is called albumen.

Albumen is formed in chicken eggs from the layers of secretions of the anterior section of the hen's oviduct during the passage of the egg and it forms around fertilized and unfertilized egg yolks.

You can candle an egg to see if it's fertile.

If the egg is fertile, then you should see a dark spot around the middle of the egg, with some spider-like veins beginning to form around it.

If its not, you should just be able to see the shape of the yellow yolk inside the egg, without any signs of an embryo or veins.

You can tell if an egg has been fertilized by cracking the egg open and if the egg is fertilized then you should notice a small white spot on the top of the egg yolk that is around 4 mm in width.

The white spot on the top of the egg yolk is called the germinal disc and this is what tells you if the egg has become fertilized.

The disc is formed with a single cell from the female chicken and a single sperm from the male chicken.

An unfertilized egg cannot become fertilized if there's no rooster.

A rooster has to be around to make the egg fertilized.

Chickens or hens can lay eggs without hens but they are not fertilized eggs.

No rooster means that there's zero possibility of the egg ever becoming fertilized.

You can tell if an egg has a chick in it by shining a flashlight into the eggshell and look for a baby chick or chick embryo.

Also a chicken egg is fertile when you see a dark spot around the middle of the egg with some spider like veins beginning to form around it.

If the egg is not fertile you should just be able to see the shape of the yellow yolk inside the egg without any signs of veins or an embryo.

Chickens are happier with a rooster although you do not require or need a rooster with the chickens for the chickens or hens to lay eggs.

Chickens and hens have the ability to lay eggs even without a rooster although a rooster is needed to fertilize the eggs that a chicken or hens lay.

Roosters do not have the same reproductive anatomy as a hen and while roosters do have the ability to fertilize a hen's egg they lack the ovaries and oviduct along with other biological features that make it impossible to lay eggs.

Unfertilized eggs cannot ever hatch as the unfertilized eggs will never be able to develop a chick in them even if the mother hen incubates the egg.

Fertilized eggs on the other hand can develop into a chick and hatch under the right circumstances.

The eggs we eat are unfertilized and not fertilized as all eggs sold for human consumption are non fertilized eggs.

You can consume Fertilized eggs as fertilized eggs are safe to eat and are edible.

You can eat eggs if you have a rooster although it's important that you collect the eggs very regularly and often enough to prevent the broody hen from starting to incubate the eggs you want to eat.

However you can also still eat fertilized eggs but you need to eat them quick enough so that they don't turn into a baby chick.

Fertilized eggs and non fertilized eggs are nutritionally the same and both are good for you.

You can eat rooster meat as rooster meat is edible although rooster meat is not commonly found in the grocery store or marketplace.

Also the meat of a rooster is more challenging than regular chicken hens because it has not been bred to grow fast and heavy like fryer chickens or broiler hens.

You should cook the rooster meat low and slow for best results.

Also rooster meat tastes just like chicken.

However, most people find rooster meat to be far more intense than hen meat — akin to dark meat turkey.

This is because of the rooster's dense collection of muscle fibers.

A capon is a male chicken that is gelded, or castrated, at a young age, and then fed a rich diet of milk or porridge.

Larger than a chicken, a bit smaller than a turkey, but more flavorful than either, capons are full breasted with tender, juicy, flavorful meat that is well suited to roasting.

The best time to harvest roosters is when they are newly matured.

For most breeds, this happens around five months of age, depending on the species.

However, it's only six to eight weeks for the increasingly popular Jumbo Cornish X Rocks (also called cornish cross broiler).

Roosters have two bean-shaped testes located against their backbone in front of the kidneys.

Rooster testicles vary in size based on their age and time of year.

Roosters are exclusively male chickens, while hens are exclusively female chickens.

There are many differences between roosters vs hens.

The primary difference lies in the gender of these two birds, as roosters are exclusively male and hens are exclusively female chickens.
