Simple guide on how chickens lay eggs

This article will be focused on how chickens lay eggs, and it will be rightly explained for your consumption, and expansion of knowledge. It takes 24-26 hours for each egg to develop which is broken down into four main parts below.

  • The releases of Yolk which takes 15 minutes

The thousands of potential eggs are located within each hen’s developing ovary. Each of these possible eggs is an ovum or ova if you want to refer to them all at once.

At any rate, when your hen reaches the laying age that can be approximately five months in some breeds, longer in others, some of the ova inside a hen’s ovary begin to grow into what we know as an egg yolk.

Each ovum or yolk is within its own follicle. At any rate, when your hen reaches the laying age that in some breeds can be about five months, in others, some of the ova within the ovary of a hen begins to grow into what we know as an egg yolk.

  • The White Forms which is about four hours or more

The yolk exits the ovary and joins the oviduct through the infundibulum, or oviduct entry. This is where if you had a rooster, the egg would be fertilized.

You know the small whitish spot you see on every yolk of the eggs? This is a single female cell named a blastodisk.

If your rooster sperm fertilizes it, then cell division and embryo development begins and transforms the blastodisk into what we call a blastoderm.

However, whether or not it is fertilized, the yolk, now known as a blastodisk or blastoderm flows down the magnum and isthmus parts of the oviduct.

This is where most of the albumen called the egg white forms around the yolk, and a thin outer shell membrane holds everything together loosely.

Chalazae anchor the yolk in the middle of the shell, approximately. The egg looks more like an egg at this point, but we still miss out on the outer shell.

  • The Eggshell about 21 + hours

The process of egg formation continues as the egg gains its shell through a shell gland at the uterus. The shell takes about 20 hours to form and maybe another hour to apply the color, or pigment, to the outer eggshell.

Whether blue, white, brown, or green, this is where the eggshell gets its color. The outermost layer of the eggshell is eventually known as the bloom or cuticle. The outermost layer forms an anti-microbial defensive layer on the body.

  • The Nest Box

Your hens lay eggs, through their vent or what we call the cloacas. Although eggs exit through the same vent that a chicken excretes for all, the uterus tissue stretches with the egg until the egg is fully out of the vent. This little trick together with the layer of the bloom added to the shell holds the egg clean.

When a hen lays down for about half an hour, the cycle starts all over again. You don’t need one nest box per hen, but you should have at least one nest box per four hens for each.
