So we took the boys to the vet and Godfrey has eye drops (wish us luck) but the vet said we should neuter the pigs?! Because it means they can live together...
I'm kind of against this, I don't think I want the risk even though they're both young and healthy. Any advice?
Neutering won't make fighting boars live together, sorry. It doesn't change their social behaviours (which includes mounting), it doesn't change their personality (a bully stays a bully, and two dominant boars will still clash) and it also won't curb their hormones all that much nor will their hormones die down instantly.
All it takes away is basically the ability to make babies so a boar can live safely with a sow after a 6 weeks safety wait. The little baby in my avatar on the left is the unplanned daughter of a supposedly over 5 weeks post-op boar (not one of mine), just to prove that point. She is not the only case I have come across.
I have currently got a boar pair where the adult (neutered) boar failed to get on with any sows he met, but reacted much more positively to my various husboars during roaming time. So he has now got a little teenage boarfriend, who I had neutered in January for safety reasons in case there is an accidental meeting with one of my many sows.
Nye is still going through all the normal stages of teenagehood. We had the testing period around 6 months when his juices were running sky-high and I needed to split him for a couple of days to calm him down again after he ended up with a rather scratched nose. He is at the moment firmly in the taxing 8-10 months period where he is constantly pestering his companion right up at the line, but is generally careful to not step over it - although he is sporting another scratch on his nose again.
The two boys get on well, are close and are well matched personality-wise, but neutered or not, they are still two boys with all the trouble that hormone spikes bring!
PS: Nor does neutering take care of the boars stink. Neutered boars can still crank out testosterone laden pee if they get excited. My recently adopted neutere Pioden would fail any exhaust test. I currently live the appealing stink of a pair of very well matured worn sweaty socks in my living room...
I still think that if it is just surface scratches and not deep bites, all is not lost in terms of them being able to live together again. As long as they have only hideys that have two exits, as my own two boys do. This especially if there are no hostilities through the bars, they interact without stiff bodies/fur standing up etc. and there is not one boar that is suddenly looking much happier when away from the other. It means that the bond is not yet broken permanently. But you have to wait until your boars are healed up again.
If you want to neuter your boys so they can ultimately live with a sow or two each (your set-up allows that without any further changes), I would recommend to contact rescues in your area to ask them for piggy savvy neutering vet recommendations so you can then bring your boys for sow dating at the rescue 6 weeks later. They will know which vets are exerienced with boar neutering.

I agree, I would also personally not trust a vet to neuter my boars if he recommended it for keeping boars together, as he is obviously not all that piggy savvy.
