I have a flock of 2 roos and 7 hens. I bought what were supposed to be sexed pullets but got stuck with 2 roos somehow. Well needless to say the 2 boys fight so Stew lives in the run and house with the girls and Brewster Roo gets to be our "yard rooster" all by himself. I lock him up in an old dog cage at night and he roosts on an old lawn chair. I opted to keep him in the yard because he got aggressive toward me when I would come in the run. Stew on the other hand has not shown any aggression toward me. When loose in the yard Brewster Roo has never gotten aggressive with me and I think his aggression was because he was protecting the girls. Well today I took Brewster Roo a treat and he did the cluck cluck cluck as if he were calling the girls. Then when they didn't come he took the bread crust over to the run to try to feed it to them. I think he is lonely. I am considering adding 3 more chickens to my flock and I am considering letting them freerange all day with Brewster Roo. My question is if I do this will his aggressive behavior return? Has anyone else kept a rooster seperated from the flock and what were your experiences with it?
