We had 6 chickens in two little families. Each with a rooster and two hens. The older set at 5 months. The younger at 3. They are free range during the day and all got along terrifically. Two days ago the neighbor's dog attacked and killed a hen and injured the rooster in the younger family. I separated the injured rooster, a delaware, in the house for a day. Yesterday I put him in a separated section of the coop. I didn't secure it well and the older rooster, a sex-linked, got in and attacked. My question is this, when the injured roo heals, will he ever be able to go safely back to the flock?
