I have a totally different management style. I don't touch my birds. I have a rooster who is four years old and I haven't touched him since he was a hatchling. Same with my coming one year roos. My key is body language and space. I make all my birds move away from me when they're young, and continue that with the roosters as they get older. I don't chase them, really (coop isn't that big), but I do move toward them and keep moving until they yield to me and move away. This is a very simple way to assert dominance. In the animal world, whoever moves away is subordinate. If you watch a mature rooster and younger roosters, sometimes the older guy will just tear after the young buck, making him run away. I do that once in a while, or if I think a young bird is getting a little too disrespectful, but mostly just make them move away. I do this pretty much every time I'm in the pen, and have not really been challenged. I will say, if they do start to challenge you, it may be time to just get rid of them. I had a bantam rooster who started attacking me at 18 months old. I tried lots of different things and he just wouldn't give it up, so he had to go.
