If anyone has actually managed to rehabilitate an aggressive, vicious rooster, I'd like to hear about it. I've had several lovely roosters and two bad ones. One scalped a hen but was fine with people. The other became vicious toward people, including me. They both came to the same end. I would not rehome a problem rooster; I would feel terrible if such a bird inflicted an injury on an unsuspecting person, bird or animal, especially a child. We tried correcting the problem behavior with failed results. A rooster can do serious damage, and around here, at least, we now have a "one strike, you're soup" policy.
