dont use a feeder. Take you some post hole diggers out and dig a few holes as deep as you can. Fill them half way with corn then pour a pack of dry strawberry jello in the hole. Then top off the holes with corn. Throw some corn all over to help attrack the guys. The hogs will find the holes and dig at them for days, depending on how hard the soil is. You can use sour corn, but the corn and jello trick works as well and you dont have to deal with nasty sour corn.
