Best wishes with your flock. If your boy is aggressive with you or the flock, it may be time to remove him. Chicken keeping should be fun for you and the other birds.
Ditch the mean boy. A pleasant rooster is a joy to have around. A mean one is the source of constant stress. Some can be rehabilitated with a LOT of effort but if there is anyone on the property that could be injured by him, you need to be aware of the liability he poses to you. Good luck.
