I have a mated pair of Rouens, Ella and Sam. They're a little over a year old and Ella has been laying eggs for awhile now. They have a very large coop/run area with a swimming pool and plenty of space to roam, but when I clean out their run I let them out into the fenced in part of their yard. I also let our 6 female chickens out into the yard to explore at that time as well. Recently Sam has started charging me when I go into his run, or even when I walk past it. My response has been to pick him up and carry him around a bit, and sometimes I tell him "no" and he backs off. He also charges my chickens and for the most part they run away, but the dominant hen has recently been challenging him and they pretty much go toe to toe, with Dora (the hen) all puffed up and Sam hissing at her. Eventually Sam will back off from Dora. What I'd like to know is how can I change this behavior in Sam? Or more specifically, can I change this behavior in Sam? I think if Dora wanted to she could kick the crap out of him.
