Thank you very much for your suggestions! I'm feeling better about being able to handle this situation now that I have several things lined up. I didnt respray on her but the wound looked a bit better today so I assume it must have worked on some level and they didn't peck more at her. She pecked at her own back after I sprayed it on and I could tell she didnt like the taste of it. The spray I have,the reviews were good and the lady at shur gain used it on her hens with success. Now I need to find who the bully is. I noticed there arent as many feathers laying around so either they aren't shedding as much or someone is eating the feathers.
As for my very injured one. She keeps eating and drinking but not moving much and staying close to her heat lamp. I will keep motoring and hopefully with some of those suggestions you had, no infection will set it. Thank you
