rush creek,

As others have said, a hog will eat anything, and if you keep it out all the time they'll actually learn your vehicle/atv and meet you driving to your feeder location.

Some of the things I've seen used, watermelons/cantaloupes, onions, corn, candy syrup from candy factory, even dead chickens from chicken houses, old cooking oil from restaurants, you name it, they'll eat it. A hog will even eat their young. A word to the wise though, they will multiply pretty rapidly and you could end up with a big hog problem.

When I retired in l987 and moved back home, my brother had a homemade gravity feeder fixed up that would hold 3 or 400 pounds of corn, he kept it full. One day I was riding around our club and actually counted 300 hogs (this included the pigs with sows) in one field. It was so bad you couldn't deer hunt for the hogs, as a matter of fact, they'll wipe out your acorn crop before the deer have a chance.
