The question brings a lot of aspects together. Not to worry, because they aren’t that complicated.
If you are planning to raise chickens as a major part of your poultry farm.
It’s good to know how biology in chickens works. For that, you don’t have to go back to your school.

Chickens can lay eggs often but maybe not that usual as you expect because a chicken egg takes at least 24 hours to be formed. And it’s an interesting formation to learn.

However, it completely depends upon the egg layering breed that you select. High-quality breeds can be productive with one egg per day, depending upon their nourishment and the climate.
So, there are factors that control how many eggs a chicken can lay in a day.

Some high-quality egg-laying chicken breeds can help you for good egg production.
Before understanding the best egg-laying chickens, let’s understand the egg-laying process in chickens.

When do chickens lay eggs?

It is expected for a chicken to start laying eggs when it’s around 6 months old,
According to the quality of the chicken breed, the egg-laying capacity varies, which further depends upon the environmental conditions.

For a hen to lay an egg the heat requirement should be at its peak, that’s why poultry farmers ensure warmth inside the coop.
And therefore, there’s different satisfaction to find an egg in the coop. Because it does take effort and hard work.

How do chickens lay eggs?

Now, to understand how real the egg-laying process happens in its natural form, let’s take a look at the step by step development of the egg.

When the ova turns into yolks:

After the fertilization process, the ova inside the ovary. It takes thousands of yolks for a chick to form. Once the best yolk is preferred, it goes under development for around 8 to 10 days. Later, when the yolk is ready to be dispatched, it falls into the entrance of the oviduct.

Formation of the egg white:

Inside the oviduct, a thin membrane called Vitelline covers the outer membrane of the yolk. To enrich the coating further, a thick protein called albumen is also formed, which is known as the egg white. the whole process takes around 3 hours of formation.

The chalazae that hold the Yolk:

Once the covering is done, the egg rolls down the oviduct forming another membrane called chalazae. If you have observed, chalazae are the spring-like white substances present at the two edges of the yolk.
It is what helps in the balance of the egg yolk to stay in the center, intact.

Towards the shell gland:

While it’s the journey towards the uterus or what we call the shell gland, where the egg is made to develop into an oval shape in the isthmus. there the inner and the outer shell membranes form in about 75 minutes.

Later it dives into the shell gland to complete the process of egg development. this is where the major eggshell formation happens. The color and strength are added to the shell during this process taking about 19 hours. The process requires 4 grams of calcium per shell.

However, the color of the shell depends upon the breed. In such chickens, the color of the egg(shell) is determined by the secretion of pigments, specifically known as Porphyrins.
During the shell formation, it is necessary to ensure that a good feed is served to the hen.

In the Last layer:

Before the egg is released through the hen’s vent, another ultimate coating is done once it has left the uterus. The protective layer is Bloom. A layer of lubricant is also added to Bloom for a smooth exit.

This is how the egg emerges to repeat the same process until the hen has enough eggs.
There’s a 30 minutes gap after laying every egg before the process continues.
