I've read that in colonial times, people simply let pigs loose in the woods, then hunted them down later on when they were fattened up.

People still do that but it’s generally not a good idea for many reasons. Feral hogs destroy crops, are dangerous to people, and eat foods that native species rely on to survive. In colonial times, it made a lot of sense to do that, but not so much now.

This won’t give you predictable yields. Though a combination of that idea and automation could work.
