I thought I had a rooster (I bought him as a male) but today I saw him sitting in a nest and when he got up there was an egg..... So, I have another pen with 2 roosters so I thought I would move one with the hens..... That was a disaster. Talk about fighting. I had to get in there and get him out or the girls would have killed him! Is it possible to put a rooster in with hens when they are older? If so, how would you introduce them to the flock without the hens killing him?
