We've just got 2 new chickens, kept separate from the rest of our flock so far. One quickly developed a bald patch and we realised she was plucking her own feathers, and they are not on the ground. We thought she might be eating them to get protein, so have been giving her lots of eggs to eat. The area looked like it was scabbing over and after a week, no regrowth. Today it is all bloody, so she seems to keep pecking at the same area. Any ideas on how to help her? Thank you.
