Well sir they can take below zero, snow and ice. Any of you guys ever see a grass/thatch hut these hog build for shelter? Trappers are catching 40-50 in a single drop on cell traps, helo's are shooting 100's per flight, how would you measure this problem. If you are raising anything for a profit that's livestock, exotics, crops, the hogs will eat you out of business. I have personally seen at a corn feeder a boar come out of the tall grass and take after an axis doe that was eating corn and 15 minutes later doe came circling back by running full out, mouth open and tongue hanging out and boar steadily gaining ground. This was on a property where I was working and this feeder was in front of the house and set for lunch time entertainment. They will destroy the turkey populations by wrecking out the nest and eating the eggs, they eat fawns, lambs, goats and I suspect calves as well plus wreck out the fence to get in. I road on a combine cutting milo a few years back in DHanis Texas and in the middle of the field there were acres of nada, just rough plowed earth. You cant afford to loose 25% of a field crop nor 1/2 of a herd of anything. I was daylight calling on a place on the Seco and heard somthing on my left and it was a 200# class black Russian boar sneakin up on me at 20'. They are predators no doubt. They are eatable and no season, feed the hungry.
