How do hens lay unfertilized eggs?

Hens lay unfertilized eggs because they don't need a rooster to stimulate egg production. Here's how it works:

* Hormonal Cycle: A hen's body naturally cycles through hormones, preparing it to lay eggs.

* Egg Formation: The yolk develops in the ovary. Once mature, it is released and travels to the oviduct.

* Oviduct Process: As the yolk moves through the oviduct, it is coated with albumen (egg white), membranes, and a shell.

* No Fertilization: In the absence of a rooster, the egg remains unfertilized because there is no sperm to fuse with the yolk.

Why do hens lay unfertilized eggs?

* Evolutionary Purpose: This ensures that hens can lay eggs even if they are not in a flock with a rooster. This increases the chances of survival for the species, as the eggs can be used as a food source for chicks.

* Hormonal Control: The hormones responsible for egg production are driven by internal mechanisms, not the presence of a rooster.

In short: Hens have evolved to lay eggs regardless of whether they have been mated. This is a natural process that ensures they can reproduce even without a rooster.
