I recently adopted a group of 5 hens and one of them has a disability regarding her feet....never stopped her but 3 days ago they ganged up on her and pecked all the feathers off of her head and past the point of blood and gave her a badly swollen eye. She had since isolated herself to the coop and i have been bringing her food and water. Today she ventured out and joined the group again and shes back to beaten and bloody. What to do?
