I have a small flock of 10 hens and 3 roosters. One of the roosters has been run-off by the other two and won't return to the coop at night. This as gone on for weeks. He has found a tree in the near by timber (right behind my neighbors house which gives him an alarm clock I'm sure he doesn't want) and refuses to go back even when chased back to it. Do I have too many roosters for 10 hens?
