Please help! I’m new here. But this morning I went outside to check on my chicks and one of the older chicks attacked her. She pulled all her feathers off her head. I separated her and the other chicks away from the 2 older ones. I cleaned her wound and applied some poultry ointment spray. I’ve only had 2 chickens that are 2 years old and we bought 3 chicks 2 months ago and I’ve been introducing them slowly and they have been fine until now. Not sure what else I can do to help her??
