You may not like the idea of using BluKote on her, but it really helps to prevent pecking, and re-pecking out of feathers by her and others. It will turn her feathers and skin dark purple, but it will eventually fad and grow out after her feathers are all in. It has to be re-applied every 3 days or so to help, but I have had head feather pecking in my polish chickens, and it has helped to heal them completely when they have been severely scalped. A bad tasting ointment such as Nustock or menthol (BenGay, etc.) might help also.
