Yeah, I bet!!!I use a gravity feeder made from 4" PVC pipe and spray painted it camo. Nearing deer season they can empty it in two days or less.
I filled up a 1200# gravity fed protein feeder with corn and figure they’ll empty it in about 30 days. I filled it with protein (dairy pellets) last year, and they emptied it in less than two weeks. I realized real quick that I can’t afford to feed protein free choice. They seem to be going slower on the corn.
