Good luck as you enter the world of boars. It is a bit different (*giggles*). I've had all boys (with one or two girls over the years). I've only once had a neutered couple. Most of the time I've had cages of boys.
Just know they tend to need more space, in every possible way.
It was my husband that suggested it was... fluids from the other pig (who actually did hump that one ALL the time).
Thankfully that's the only time that happened!
Should I tell her about boarfume? Small Head Disease?
