Best way to deal with him is to get rid of him. You also do NOT want to be keeping any roosters bred by him. You don't breed a mean rooster and continue that line. There are plenty of nice roosters around. I have a Ameracauna rooster that is borderline retarded but also takes good care of the hens. He is very nice and I didn't spend a lot of time handling him when he was young. He's not even remotely mean. A mean rooster is going to eventually seriously injure one of your kids ... or a visiting friend. They can jump high enough to get at someones face and they will try.
