When our broody hatched a cockerel we ended up with two male chickens. Since his father was already lord and master over the henhouse, and we only have nine hens, we decided to let him remain the henhouse rooster. His son, when he reached about five months old, had to be relocated to a chicken tractor next to the other birds chicken yard, because the two males could not get along. This means that poor little Pierre lives isolated from the other birds -- separated by a chicken wire fence from the girls that he would love to mount. He's none too happy about his forced celibacy, as he made perfectly clear about a week ago when one of the hens snuck out of the chicken yard when I was walking in, and Pierre mounted that bird before it even had a clue what had happened. But except for that one time, he has not had a sexual encounter with any of the hens. I have noticed that occasionally he squats down and sort of rubs his bottom on the ground. He is, for the most part, in the same position that he would be if there was a hen underneath him. Is my (now) six and a half month old cockerel "self stimulating?" What -- if anything -- can I do to help him, given the fact that he is separated from the other birds by chicken wire?
