Can you "train" roos to be nice? Or is it just that some are nice and some are jerks? I have a new one and I would hate for him to turn out like my Red, not that I could get rid of Red now, he is a jerk, but I love him anyway. I just don't want my new Barred Rock to be the same way. Oh and can they two ever free range together? Or will one always have to be cooped up?
