I have a speckled Sussex about 24-36months old. He is not interested in mating. Hasn’t meen in about 6 months. The hens will back up to him and squat then shake their tail feathers and he is clueless. Like he is no longer interested he is huge and big combed so I wouldn’t have thought it was male hormones. Any thoughts? I have a hen raising what looks to be a rooster. Cuckoo maran. But they are separated in the other side of the yard.
