thanks all for all your advice, I really appreciate it! I know there may be complications and that's one of the things that's held me back. It would be good to bond them but there's no way i can get them far enough from my girlies to keep them from being over excited! Bless them. I've tried a few days keeping the girls in and letting them out, and it's only recently they've had contact with girls through the wire. The other reason is the girls that won't bond with the others, i'm thinking that if i do get them neutered they could have a girl each but separately. So each boy'd be in a hutch each, with a lady or two rather than together with girls. This would mean they all have company whereas at the moment i have two girls living individually and two boys living individually. Would be nice to pair them. I can't understand why the girls won't get on either, i've kept guineas for over twenty years, i must have had forty or fifty at least over the years and only in the last few years have i had this issue. It's very odd but if i put jem or red with another piggy they fight. I've tried all combinations, quiet ones dominant ones, nothing works and they end up so upset. So this is my plan. . . Thanks again for the advice and link, will have a good read.
