Best way i have found is to dig a hole as deep as you can with a post hole digger. Fill it half with corn and then pour a pack of dried strawberry jello in it. Then top off the hole with corn. They will root at the holes for a few weeks. Put you out a couple of holes and I promise you it will work. OR you can make a hog feeder out of PVC pipe or a bucket. I use 4 inch PVC pipe at about 3 to 4 pluse feet long. Glue a perminant cap on one end and drill a hole through it. Thread a cable/chainthrough the end so you can anchor it. Drill a number of holes in the pipe that will allow corn to fall through. Put a screw on cap on the other end. Fill the pipe with corn, screw on the cap, and anchor the chain to a tree or something that will not allow the hogs to run off with it. The hogs will push the pipe around releasing the corn for a considerable time..
