we have had our rounds with an aggressive RR roo and we had to go in the coop with a freaking brom just to make sure he didn't try anything. soon he was in the freezer, and the next roo took over, and everything changed. he is so calm with us, but is still a very good protecter of the flock. but he doesn't even really pay me any attention. but if I get near him and he doesn't move out of the way, I will give him a quick kick, or scare him some how, to let him know to get out of my way, and not be near me. that has worked so far. he isn't nearly as confrontational as my other roos were. it is such a relief. if you don't start showing you are the boss (like your mom must do) then he will never think you are above him in the "pecking order" and will continue to terrorize you. you may have to endure a few pecks, but they will stop. if he doesn't "get it" then off to the freezer. when I cooked the other roo, it almost felt like revenge, because he went after my 6 yr old one time. I had the last bite though. good luck!
