How do we no that when a chicken lays egg not baby?

It's a common misconception that chickens lay eggs instead of babies! Here's why:

* Eggs are a form of reproduction: Chickens, like other birds, reproduce by laying eggs. The egg contains a fertilized embryo that develops into a chick.

* Eggs are not babies: The egg is a protective shell and food source for the developing chick. It's not a baby chicken itself.

* Baby chickens hatch from eggs: After about 21 days of incubation, the chick inside the egg develops and hatches, emerging as a baby chicken.

Think of it like this: A human baby develops inside its mother's womb, and then is born. A baby chicken develops inside an egg, and then hatches. Both are forms of reproduction, but the stages are different.
