My hen was attacked while I was on vacation and she was under watch by my neighbor. I think the combination of me not taking care of them a few times a day and the fact that their coop wasn't moved for too long led to the other 5 (including a roo) teaming up on her. My neighbor found her bloodied with what I believe to be her skull visible. Will this ever heal? Its been almost a month and the feathers are slowly regrowing but no signs of healing on the bare bone. She's being kept seperate from the rest of them with a steady diet of sunflower seeds and clover from the yard, along with whatever she finds on her own in the time she gets to free range.
