We have two roos and had 4 hens ranging between 3 and 5 months. They all got along very well. The neighbor's dogs attacked, killed one hen and injured the younger rooster, a delaware. I put the injured rooster in the house in a box with straw. I've been putting antibiotic cream on his injuries. He is mostly scraped up with two cuts around his tail. One is about an inch long. He is also limping. After a 1 1/2 days inside, he seems ok so I put him in a separated section of the coop. I did not secure it well and the older rooster, a golden sex-linked, got in and started attacking him. These are my questions. Am I handling the injuries correctly. There are still feathers around the cuts, with a dog or horse I would shave the hair to prevent infection, I don't know about a chicken. Second question, will the older rooster accept the injured one again, or is my cohesive little chicken family gone forever? Thanks.
