Rack Stacker Auto Feeder Deer FeedBy roasting the ingredients we have allowed the feed to be sweeter and easily digested by the deer. The feed is highly sought after when the snow flies and can be used year around for keeping the deer healthy and in the area. We have added apple flavouring to get the smell out here even more for the success of your feeding program. The Auto Feeder Mix was designed specifically for auto feeders (gravity electric feeders)
