Considering they eat a ton of dirt and vegetation to every grub, worm, snake, toad, lizard, etc., meat they eat, and you can tell this by the acreage they destroy while rooting, it is not unusual to discover the meat can taste like river bottom dirt. That is why my feeder goes 24/7/365, plus the law says it may not be hunted if it hasn't been established more than 6-months in advance of the hunt.
http://www.eregulations.com/florida/hunting/general-information/ Resident game and wild hogs may be hunted in proximity of year-round game-feeding stations on private lands, provided the feeding station has been maintained with feed for at least six months prior to taking resident game.
Individually, each animal doesn't get much. Maybe a gallon of corn total is slung per day. That's all. It is shared by deer, hogs, coons, squirrels, birds - especially turkeys, and periodically, a bear. Still that tiny amount over days and days does a remarkable job of flavoring the meat and producing a slight fat layer in hogs. At 300#'s per 55-gallon feeder replenishment and about 2-months between replenishments that's about 2000#'s of corn annually or about $500.00 annually including tax, so those harvested free range hogs are not "free" - per se. The "price of admission" to my guests is a couple of bags of corn, then kill all the hogs you want when they participate, and there is no guarantee.
