I had a very human aggressive white Phoenix Roo that was given to me because he was so aggressive. He would leap up at your face, bite and spur you and keep coming no matter what you did or how far away you were.. 1. I cut his spurs, 2. Every time he came at me I grabbed him and put him under my arm while holding his feet. I took him with me feeding up, yard work, etc etc. If I put him down and he came towards me I grabbed him again. After awhile he stopped. He became one of my friendliest roos and no longer went after anyone. We named him Killer after his former self but he got were he would eat from my hand.
