Neighbor caught a baby wild hog and thought he would raise it like I did with Oscar. His kids loved on him all the time, but even after getting him cut, he could never be trusted, so after about a year, they let him go. We saw him from time to time, he'd just walk out of the brush like he didn't care anybody was there, and walk right past you. I never felt right shooting him, and eventually he just wondered off. I haven't seen him in a few years and forgot all about it. I've been told by other people through FB that they also tried raising one as a pet, but it was too destructive, or aggressive. But I have no idea what they did, or how much time they spent with those hogs. With my neighbor, he kept it in a pen about 50x50 feet, away from the house. I don't think he or his kids interacted with it enough to bond. They where here on weekends, and not every weekend. He worked during the week, and I have my doubts about how much time he spent with the pig when he was home. Oscar got a lot of attention, was always around people from day one. That might be the difference.
We also have roosters and they are the devil. Of the dozen or so roosters we currently have, maybe three are great, the others are probably gonna end up in the crock pot sooner or later. I think two are going down this weekend. This year, I guess I've killed two dozen roosters. We are letting the broody hens sit on eggs and hatching them, so we've been getting a lot of new birds all year long, but mostly this past Spring. The same will happen next year when they hatch and grow up into monsters. That switch will turn in their heads and then it's time to die. Sad, because we really enjoy seeing them, and watching them wonder around the land.
