I have a RR that seems to be lowest in the pecking order. The other hens seem to pick on her a lot. But recently one in particular is getting her down on the ground and pecking at the back of her head. It is to the point now where she is loosing "hair" and is almost bald. I have no idea what to do about this. I have considered getting rid of the offending chicken. Or seperating the lowest chicken to her own area. Any suggestions short of a helmet?
