Your sentence is mostly correct! It says, "A chicken lays eggs and hatches chicks in a coop."
Here's a little explanation:
- "A chicken lays eggs" - This means the chicken makes eggs. This part is perfect!
- "and hatches chicks" - Hatching means the chicks come out of the eggs. This is also correct!
- "in a coop" - A coop is a little house where chickens live. So this means the chicken is laying eggs and looking after baby chicks in the chicken house.
So the sentence is good and easy to understand. Great job!
