I have been using corn so far this year and its great for the winter months. I dont uasully put my minerals or salt out till spring and summer. The deer just go crazy when I put it out then. The mineral and salt help with antler growth because in the spring and summer the days are longer wich makes the deer give off a hormone, so alot of minerals and protein go to there antlers at a fast rate because thats what antlers are mostly made of, so thats why I put it out in the spring and summer.
