loss of feathers on her butt

[enok]

Can anyone tell me why this is happening? I've read about chiken (need of) but nothing about butts. What should I do?

Could be mites, could be feather-picking by another chicken.

Check/dust for mites, always repeating in 7 days to kill hatching eggs (and maybe spray the coop if you haven't done that in awhile), and make sure they have enough protein in the diet. Pinless peepers on the one doing the pecking as a last resort.

Thank you for the info. I will get to it first thing Monday.
