We dont have hogs here but Coons are a big problem, I try to cater more toward feeding turkey then deer, so I used to set my feeder to go off about an hr after daylight to discourage the deer and coons, but pretty much quit using a feeder, I just walk out and broadcast a gallon or two out real thin by hand whenever I get to it, a little more regular during times when their food source is covered with snow or ice.
All the really good ideas I've ever had came to me while I was milking a cow.
