I have a 6-week old Araucana chick. Beautiful chick but its butt is completely bald and has been since we got it three weeks ago. I've watched the group of chicks, and it doesn't seem that the others are pecking at this one. However, that little bald butt is very noticeable and looks bad. It's not swollen - just bald. The chick is active, eats and drinks well - and doesn't seem to have any other problems except occasional diarrhea which dries on the bald butt and makes it look worse. Should I just chill out? Will it always be bald?
