My beloved roo, Mushmouse, started attacking me a few years ago. So I stalked him for about 10 minutes a day. Just keep making him move and move, don't let him eat drink or jump girls. Don't back away. Just keep making him move. Mine was cured by the end of the week and then became my snuggle-silkie. He would even wait for me to pick him up and put him in the coop. I don't believe in being mean about it, just talk in rooster talk that I am the BIG ROO. I've had quite a few roos that stopped the nonsense but don't fear me. I've never failed in doing this. I just love Silkie roos.
