My dog attacked one of my hens. I think she has a broken jaw as its not straight and she can't move it, and I think shes in a lot of pain. She won't eat but she drinks, and yesterday I noticed thick yellow pus leaking from her eyes and mouth and I'm afraid a bad infection is brewing. I don't know how to cull but right now I think she has a chance as she still walks around some and seems to have some energy. Is there any kind of pain meds/antibiotics guys recommend?
