Most of the farmers/ranchers here in East Texas have enough fire power to keep them at bay... Then again the sounders around here only average about 12 pigs and a few piglets, you get further west, and you're talking 30+ pigs in a group with a crap ton of piglets.
Actually back in 2008, we caught a little piglet, probably not even a week old. We had plenty of powdered milk to use for calves if they didn't nurse. She was a silly pig, ended up naming her Dixie. We never had to worry about what to do with food scraps.we even had friends rhat would bring their old expires canned food etc. And Dixie would chow down. Every fall and winter she would start gathering leaves in her mouth and she would build a nest.. I have some pictures of one on a hard drive somewhere... She died in 2017, just a month after our old dog passed.
