We have a rooster that is just over 1 year old. He's a large friendly NH red. All our hens were killed by hawks so he is our only adult bird. We have 2 month old Buff Orpington pullets that have been living in the same coop with the roo, but separated by chicken wire. They seem to be friendly with each other so we'd like to integrate them. If we do, will the roo try to mount the young pullets since he has no hens?
