I also read the rooster reform link before my roosters got an attitude, and the principles helped me a lot.
I wanted to say, raimnel, that your bantam rooster - though he's small - might be teaching bad habits to the up and coming cockerels. If he's allowed to attack you - even though it's just your ankles - then the other breeds of roosters know that you are not in charge. In fact, you're second string to 5 inch tall attitude problem. So of course they attack you.
Also, in defense of RIR roos. When i was forming my flock, a friend gave me 3 unwanted male rir chicks when they were about 6 weeks old. They were brothers, who incidentally had been brooded by a beautiful bantam couple, who did a great job. (end rabbit trail here). Anyway. I raised them all up the same, and as they crept toward maturity, i just watched how they treated the girls and how they responded to me. Eventually, i decided on my favorite, and i stewed his brothers.
Rocky is what i named the guy who was left. As i said, i had read the rooster reform business. One day, i was picking up one of the girls to give her a look-see, and she resisted and squawked at me. When she did, Rocky pecked me HARD right in the knee. This was his first painful act of aggression toward me, and i nipped it in the bud right away. After i was done looking at the pullet, i picked up Rocky, and i held his beak between my fingers, and i let him know that i'm the boss. I might have done this two more times when he looked at me in the wrong tone of voice, and now he is a spectacular rooster.
So don't discount RIRs. He is protective of his girls, gentle with them, and he watches the skies for danger. He's a great guy. We don't cuddle or anything, but he knows who's boss, and that's what counts.
My buff orpington roo is a cuddle bunny, but he also would likely be worthless at defending the flock against danger.
Oh also, my knife is ready, but i might need help with the airfare.
Glad you finally did him in.
