I might add that released domestic Hogs are breeds. line breeding or inbreeds. A study here says random breeding and they eventually revert back to the original animal or something else very near the original wild animal (kind of like a Dingo).
Yes!!!!

I've often wondered if you could train a Sow to lead a sounder back to a corral?
Maybe. She might have to fight. i've seen a few sow fights. One was between two big sows in a sounder of six sows. You could hear them fighting as they made the rounds of the feeders.
