I was told by a man who raises guinea hogs that he tried another hog breed at first and they rooted his nice pasture to mud. He switched to guineas and has not had the problem since. Instincts may have something to do with behavior as far as the rooting thing goes.
It seems like rooting stems from a combination of boredom, curiosity, and lack of things to eat above ground.

If so, for how long?
We were going to process little castrated boar around March time but do we need to keep him for longer to be company for Mr Boar if he needs to be kept separate?
