Ad, mostly they aren't to bad, i combat males a bit even if it's not really needed, it gives them a spring in their step and always mate well after.
Sometimes they can get a bit narky and will bite but normally it's just a whole lot of running around the cage and a bit of a wrestle.
Always watch them while theres two males in the cage, i normally leave them together for about 10mins unless they starting biting. I've never had any injuries from the bite as they are more a nip than anything, if one does bite i will separate them straight away. It would take alot of biting for a maccie to to any damage to another.
