My first rooster was a HUGE Golden Comet- he got more agressive as he matured. I had never heard of BYC, no one I knew had ever had chickens, but I knew how pecking order works. He didn't respond to any friendly overtures, and finally I just flat got mad.
I backed his big ol'self into a corner of the pen, reared up as big as I could, loomed over him with my "wings" up and over him, made a bunch of really terrible noises and basically scared him ****less. I mean I really flapped and roared at him! I had to do it one more time, which was unfortunately witnessed by DH, but that did it. I was established as the alpha roo. Even though I'm not a roo.
I have a Golden Sebright roo, itty bitty guy, and not even that has worked with him. He has spurred my leg twice, and I intend to try the "hanging" approach with him. Gently as possible, of course.
Now I have a brand new 6 month EE roo. He is a rescued bird, and terrified of people as a result. He has real panic attacks when I enter his pen. Before I put him in with his betrothed 7 BR hens, I intend to spend a lot of time trying to let him know he can trust me to never hurt him. So I'll just sit down with a beer, (therapy for me, too!), and let him approach me.
I guess I'm saying it depends on the roo as to what approach to take. Good luck!
