I recently started my own home flock of chicks. I've done a lot of reading and have asked fellow chicken owners many questions/suggestions as I go. One of the things that i've learned about is "pasty butt". Well, one of my little orpingtons has had a mild case of it. I've been checking on her everyday and cleaning her up as needed and it appears that the problem has cleared up. However she has started plucking out the little down feathers all around her behind. I've watched and the other chicks are not picking on her and she's doing it herself. Should I be concerned? or should I just let things run the natural course? She healthy and just as active as the other chicks are.
