You could brake a dog or a rooster of a habit, just like a person . It was just suggestion, but what's the difference between a dog or a rooster both can be violent and BOTH can be broke. A rooster is a animal. Just like the dog, but we kill one and not the other!! Dog abuse is illegal, but you can cull a rooster for the same reason. It is the way you act around him if he likes the reaction he will keep doing it. At the end I said "if he doesn't change kill, sell or give away" if you don't give him a chance you might miss out on a good sweet rooster. Pick one person to feed water and gather eggs. Wack,or flip him over, him every time he gets aggressive. Do not let your son in the pen.after the first few times of wacking doesn't work the sell or cull.
