Hopefully it doesn’t come to anything and you don’t need to separate them but having a plan is always good.
I know it’s upsetting. I know I’ve told you that I have a bonded pair of boys and then two singles. When the two young boys fell out, although I had a plan, it just threw everything into a bit of chaos!
It’s not a case of one or two sows being better as such - it all comes down to character and how well they can form a bond.
The issue with odd numbers of piggies is that there can be an outsider situation - two can end up closer and one gets left out. The sows will have a hierarchy between them which the boar is not part of. He is only part of group hierarchy. If the sows have any kind of disagreement the boar is likely to side with one the sows.
With that said there are many many happy mixed sex trios!
A 2x5 is big enough for a boar and two sows though.
If you need to save space then the two cages can be stacked on top of one another (but only once they are bonded with another piggy - during any time they are single they must remain side by side)
The best way to find a new friend(s) is with the help of a rescue centre (once neutered and six week post op safe). They can help ensure compatibility. Some bonded sows just won’t accept another piggy in with them, even a boar, but that tends to be a bit more when they are older.
