A neighbor's hen is free ranging in my yard. All my chickens live in an enclosed coop/run setup. This one has been trying to get in and then hiding in the bushes when I go out there. I'm pretty sure she attacked my cat last night, who also free ranges. It looks like he was pecked hard in the back of the neck. I'm going to ask around the neighborhood about her. What breed do you think she is? What would you do about her?
