As Karen says
don't mix him with any boars, they will fight.
So long as he can see other pigs he should be fine. Our boar is between ladies at the moment and i think he's savouring the peace and quiet
but not for long another young lady is due any day, so back to work!
When you introduce him to your ladies it would be better to bring them to him if you can, then he won't be so bullyish with them. if you take him to them he will spend a lot of time marking his turf and throwing his weight around to make them know he's boss.
