Is it normal for a chick to eat grass?

[CowGirlchicklover77]

My chick is around 2 weeks old and is a plymouth rock and she is eating grass my other chicks (golden comets) dont eat grass so is it ok for her to eat grass?

Most normal chickens eat grass. I think it's your other ones that are wierd.
