Hey all I've got 3 buff laced polish and 4 buff brahma chicks that are 6 weeks old now and all of the birds have been pecking on one of my polish chicks and have pulled alot of the feathers of of her back and her back is now just raw. We have separated the birds now but you can tell that she is hurting and flys keep landing on the sore places on the injured ones back. Is there anything I can do to keep the flys away or something I can put on her back to make her feel better? Please help me I'm not sure what to do.
