A while ago I had an aggressive rooster who rode my girl so hard he balded her back. Tore out so many feathers and hurt her skin. He is no longer with us and it doesn't seem like her feathers are growing back. Do I buy a feather fixer feed? Do the feathers grow back? I feel bad for my girl - she's all black with green sheen and so bald on her back. :( Poor girl. her skin is fine, she isn't red or irritated and it doesn't bother her. What should I do?
