Hi! Your two boys have unfortunately hit the teenage hormones and are not working out as a pair if they are clashing that badly so early on and with another 10 months of hormones still to go. How big is their cage?
Unlike with rabbits, neutering boars will not bring them back together, but it will enable them to live with a sow each after a six weeks' post op safety wait. Cross gender bondings are the most stable of them all once initial acceptance has happened. I would strongly recommend to look for either a general vet with plenty of guinea pig neutering practice or an exotics vet with experience in small animal ops. We have got a piggy savvy vet locator on the top bar. We have also got a good standard rescues locator so you can date your boys under expert supervision to make sure that you end up with two love matches and no accidentally pregnant/completely healthy sows. You can consider keeping the pairs on top of each other, so you do not lose any more space.
PS: I have got a surprise baby courtesy of a supposedly safe over 5 weeks post op boar, just to make the point of the 6 weeks wait.
Please make sure that you disinfect their wounds and have them checked by a vet if there have been bite wounds. You can make saline solution by mixing 1 teaspoon of salt into 1 pint of boiled, cooled water; alternatively you can sterile saline at your pharmacy. Keep an eye out for potential abscesses in the days to come and see a vet asap.
