I have two young cockerels that were the only two chicks that made it out of a poor hatch last spring. They're about 7 months old now, and very easy going to have around the place, compared with my big old nasty Marans roo who I just ate last weekend. They go everywhere and do everything together. They stomp about the yard side by side like a pair of funny twins that always wear matching clothes and it's really comical. They're friendly to me in a kind of standoffish way and have never shown the slightest hint of aggressiveness to anyone. But I'm a bit worried about how they act with the hens. When I say they do everything together I really do mean EVERYTHING. Ahem. I've nicknamed them the tag team shaggers and I'll apologise in advance in case I'm offending any delicate sensibilities. But when they're romancing one of my ladies, one of them will grab her by the neck feathers with his beak while the other one jumps on top and does the deed. Then they swap places. Is this normal behaviour? I thought roos would always compete for top position. Anyway, I have 13 hens which I thought would be enough, but I think they may have taken a shine to one in particular, as I have just noticed that she has small bare patches on her shoulder area. Should I be worried?
