Hi all. My 1 Rhode Island red is VERY aggressive with all of the younger chicks. I have been trying to integrate them slowly. They are only about 4 weeks apart. We have started letting the 2 groups out in the yard at the same time. They still primarily stick to their own groups but the RIR will go out of its way to chase and peck at the little ones. Is this normal pecking order? When they were in a cage it was easier to peck it on the head when it happened. But out in the yard I can never get close enough. I am ready to get rid of it. Not sure yet if it's a roo or hen.
