An animal feeder apparatus including a feed hopper defining an interior for receiving a quantity of feed, an upper opening and a lower feed discharge opening. A feed shelf may be located below the feed hopper and have an upper feed support surface with at least a portion of the upper feed support surface being located directly below the feed discharge opening of the feed hopper. A feed trough may be located toward the bottom of the apparatus below the feed hopper and below the feed shelf, and form a lower feed support surface upon which feed falling from the hopper and shelf rests. A feed shelf movement assembly may be configured to permit a feeding animal to move the feed shelf from a location adjacent to the lower feed support surface of the feed trough.
