Sully, IA, hog farmer Arvin DeCook designed and installed a Ground-Level Pen Walk-In Feeder. It extends from the pen fence into the pen and is wide enough to enter with feed buckets. Fences on both sides of the feeder are gapped such that hogs can get to the feed but not into the feeder. The end of the feeder is blocked off with hog panels. (This device could be used for all types of penned livestock.)
