I have successfully dominance trained several roosters with this method, most of the technique coming from Bee kissed who has 40 years of successful flock mastery under her belt. I can guarantee that backing away from a roo will encourage the aggression, and not stop it. I can also state that feeding a roo out of bare hands is invitation for a skin wound. But, everybody has their own methods for working with their own flocks, and what works for one might not work for an other.if you act like another rooster around him, it will make things worse actually. if you chase him, he will constantly attack you, thinking you are another rooster. but i agree on the first part, a human aggressive rooster should NOT be tolerated. if he tries to attack, i would suggest gently backing away. also, don't make quick/threatening movements around him and don't carry large things around him.try feeding him out of your hands.
