Taming a roo you haven't raised from a chick is going to be a challenge. And the breed of your roo isn't in your favor, either. I think the most you can hope for is to develop trust, so he'll respect you. I think you should give up on the idea he'll ever be as tame as your hens.
To start the process, you need to monitor your behavior and be consistently calm and slow. No sudden movements, and any small children must not be allowed near him. His nature is to protect the hens and dominate them. Any confusing activity will make him nervous and anxious, therefore combative.
In order to get him to come to you when you need to put him in the pen will require establishing trust beforehand. Food is the way to do this. Take something that you can hang onto while he nibbles from it, like a crust of bread. Squat down and hold it out. This will take several days to accomplish. Over this time, gradually pull the food in closer to you so he's within touching range. As he eats, slowly touch him as he eats. This will get him to trust your hands. If he's so skittish that he won't take a treat from you, then use his crumbles, beginning early in the day before he has a chance to eat and is hungry.
If you don't want to go to all this bother of training him, you can be assured he'll come back to the pen when the hens go back in.
How old is this roo? How was he treated where he came from? Do you have kids? How old are they? These are all factors that will be important to consider when training this rooster.
