My question is . . . can my hen regrow skin which in turn would give her the capacity to grow feathers? Apparently she was attacked by a hawk which dug its beak into her back making like a ditch all the way across her back. It also ripped off her skin and feathers on her back. She is completely bare except the feathers on her neck are covering the area so the other chickens don't see it. Can she repair or do I need to replace her? She is a bar rock if that matters and won't be a year old until March or April.
