The chicken life cycle consists of several stages:

1. Egg: The life cycle of a chicken begins with an egg. The egg is laid by the hen and contains all the nutrients needed for the embryo to develop.

2. Incubation: The egg is then incubated for 21 days. During this time, the embryo develops and grows inside the egg.

3. Hatching: After 21 days, the chick hatches from the egg. The chick is covered in down feathers and is completely dependent on its mother for food and warmth.

4. Brooding: The mother hen will keep the chicks warm and protected for the first few weeks of their lives. During this time, the chicks will grow rapidly and develop their feathers.

5. Juvenile: After a few weeks, the chicks will start to venture out on their own and explore their surroundings. They will continue to grow and develop until they reach maturity.

6. Maturity: Once the chickens reach maturity, they will start to lay eggs of their own and the cycle will begin again.

Overall, the chicken life cycle takes about 6-7 months from hatching to maturity.
