I just brought home four Hereford pigs that are about 8 weeks old. I started them out in one of my chicken tractors to provide protection. I want to pasture raise these pigs but I'm worried about potential predators. Do I need to worry about coyotes and other predators or can I just put up a couple of stands of hot wire? I could always use feed to lure them back into a tractor for the evening I guess. Your advice would be much appreciated.
