Does a chicken has 4 STAGES?

That's not quite right! Chickens don't have 4 "stages" in the way you might be thinking. They have a life cycle that includes these main stages:

* Egg: A fertilized egg is the beginning of a chicken's life.

* Hatchling (Chick): The chick emerges from the egg.

* Juvenile: The young chicken grows feathers and begins to develop adult features.

* Adult: The chicken is fully grown and capable of laying eggs (hens) or mating (roosters).

Let me know if you'd like more information on any of these stages!
