One of my Barred Rock hens flew out of the run and was attacked by my dog 3 days ago. The dog basically tore up the top of her back from her neck to her tail. An area approx 2 inches wide and 6 inches long. It was a bloody mess. I took her across the street and had my neighbor check her as he also has chickens and he said she only had tissue damage and would be fine. She is eating and drinking. Bleeding stopped on Saturday. I went to Pet Smart and picked up some Hydrocortisone Spray and have been applying that twice a day. I did not bandage since it is such a large area. I do notice a smell but am thinking that is the medicine??? I am keeping her separate from the other chickens at night and during the day except for when they free range in the evening for a couple of hours. The other chickens are not picking on her at all when she is free ranging. Do I need to do more or am I too late? Please tell me what to do at this point....
