Pearl seems really sweet, and he seems like a good boy! The fact that he trusts that you'll keep him safe is really cute! But Cocoa is being a jerk, and if he were mine, I'd probably do what you're planning to do. Just make sure Pearl isn't being picked on too much, roosters can be very aggressive to other roos. I have 5 meat-birds, 2 of the RIRs are roosters. The dominant one is very mean to me and to the other roo. He bites, chases and attacks the roo, and me too! When I pull out food most of my hens come running to eat out of my hands, and even the sweet less dominant roo comes to me and eats! Unfortunately, even if he's trying to be gentle, he ends up biting really hard, so I pull back and most of the time I don't let him eat out of my hands because he doesn't know how to be gentle.. But sometimes I make sure he gets more treats, because he's a good boy. But, I used to think he was the mean roo... So I did yell at him sometimes, and even though he'll eat out of my hands, he won't be touched, picked up, or followed.. He'll run. But it's okay, I mean, I kind of get it. He is being traumatized by the mean roo. (Which by the way, I'm hopefully getting rid of soon.) But my problem is.. I love some of the meat-birds because they're really sweet.. But I promised that I wouldn't keep them.. I've been trying not to get attached, but it's so hard..
They are all currently in the coop and run together -- so far so good. I'm not holding out too much hope that the calm will last. Pearl really has been good and today has been wanting protection. He's a bit of a sissy/mama's boy lol.
I would like to have meat chickens as well, but not sure if I'm up to the task of butchering. I can clean fish no problem and assisted in dressing a deer that was hit by a car in front of my house. I think once I do the first it should be easier.
Still waiting for mine to start laying! 
Best of luck.
