Can vulterine guinea fowl and regular guinea fowl live together?

Answer 1

Yes. I used to own both. Never had any problems. They were in quite a large pen. I'm not sure how they'd do in enclosed spaces. But chickens don't even do well with other chickens in enclosed spaces. They'll start picking at each other. So, as long as you've got adequate space, you should be fine keeping a rooster and a male guinea fowl together. (Although we always had hens and guinea hens as well, not sure if it'd make a difference if you just had the males alone without any females.)

Answer 2

Yes, absolutely.
