I have used 2 methods the most effective is to send to freezer camp, they never attack any one again. I have also had moderate success with carrying them around while doing chores in the yard. I really wanted to get some chicks from my Lakenvelder, and he has stayed out of my way after the 4th time I grabbed him up after he went after me. He still tries to go after my 22yr old grand son, if he goes after the young kids, he will have to go!!! The best way to make sure your roos are gentle is to handle them a lot when they are chicks..... good luck with yours,but remember roosters are easy to come by many people give them away for free. I have given away 3or4 myself,they were nice but I had to many.
