This afternoon we integrated a 24 week old Barred Rock rooster to our existing 4 RIR hens that are 16 weeks old. We got him from a neighbor who had a RIR rooster and a Barred Rock rooster. I was told that the Barred Rock was not aggressive and liked to be picked up. The RIR rooster bullied the Barred Rock rooster quite a bit and was described as pretty aggressive. The Barred Rock is missing quite a few feathers from his tail caused by the aggressive RIR rooster. So far he has not bothered the RIR hens at all. In fact, a couple of the hens have pecked him and he just stood his ground and then jumped straight up to shew the hen away. They have only been together for a few hours. Now they are all in the coop settling in for the night. So far so good. Anyone have experience with a Barred Rock rooster with RIR hens?
