What is the difference between a chick and chicken?

* Chick: A baby chicken, usually less than a few weeks old.

* Chicken: A fully grown, mature bird, typically over a few months old.

Here's a breakdown:

* Chick is the term used for a baby chicken, regardless of its sex.

* Chicken is the general term for a mature bird, also regardless of its sex.

So, a chick will eventually grow into a chicken. It's like calling a human baby a "baby" and then calling them a "person" when they grow up.
