i hatched chicks mother nature's way and i'm wondering when i should seperate them from the mom. they are almost fully feathered except for certain parts on the back and they are just getting feathers on the head. they are too big to fit under her and she just laid and egg today. she is also starting to peck at them a little when she would usually give them the bugs she finds she doesn't do it as much now. they are about a month and a week old.
