To me it sounds like you are kind of taunting him and it's not your fault- you don't know how to react. Good thing you are asking for help. My RIR rooster was a real jerk and still is from time to time- I could not get close enough during his attack to push him to the ground. I kicked him and I made it count- all the time hoping I did not hurt him.
But, he asked for it and has since been pretty respectful. He is still ornery, but ornery I can handle. I can't have a mean roo at my house. Too many kids and visitors for that business.
Whatever you do, I think you need to make it worth while. Get the point across big or he won't get it. Not saying booting him is a wise choice, but sometimes you gotta work with what you got. (I also carry a golf club-- to poke mine when he thinks he wants to go another round to deter him... I want to clarify that I would never swing the club unless I wanted to make sure he never got back up.)
Oh, and Farm_Maven, your roo looks just like my sweet, sweet Leroy- who I WISH would kick Big Red's hiney and become Alpha!
