A friend caught seven in a trap the day after Christmas, he put them in a stock trailer so he could haul them to a buyer. Whe he checked the trap the next morning he had sixteen...........one of the old sows had dropped a litter overnight. He cut her and the pigglets out and penned them up on his place, they will eat well in a few weeks.
We were overrun with hogs earl in the deer season, but after taking ten or so off the place I haven't seen one in over three weeks.......we couldn't be so lucky that they are all gone, but it would be nice if they were.
jamaayton, you are doing right by killing the sows, that stop, or slows the reproduction process, and causes the boars to move on.
