I have 33 hens and 1 roo. My only RIR hen has made me her best friend. She gets picked on a lot by the others. When I am outside, she runs over and follows me everywhere. When the others run over to us, she will jump up at me begging to be picked up. She loves to walk around in my arms. The sweetest thing in the world. The only aggression she has ever shown has been toward my dog and the rooster. She DID NOT appreciate his advances and let him know!!
