The good news about raising pigs is that they are smart (although I suppose this can also be a bit of bad news, too!). Pigs are like dogs in that they will run loose all day but ultimately they will want to come home. Of course that’s not always the case - that’s why feral pigs are such a problem, after all. However, chances are, as long as you don’t let your pigs wander too far and have plenty of incentives for them to come back (shelter, food, water, etc.) then they should come home. But it’s far easier to initiate these tips for preventing pigs from escaping than it is to try to clean up after the fact - or wait around for your pigs to return. So take steps now to keep those pigs where they should be - home!
