So I just got my baby chicks in the mail on Friday and I'm finding that all Im doing is worrying about pasty butt. I check the chicks butts all day long and if I see any poop at all I wash it off. Is this what Im supposed to be doing? or if its just a little bit am I supposed to leave it? These are my first chicks. Oh and do they grow out of this, and if so about when? Thanks so much!
