An animal feeder configured to provide feed to animals via gravity actuation is disclosed. The animal feeder may be configured such that feed is contained within a feed container and provided to animals via gravity and through an outlet opening configured to eliminate stagnant pockets and feed spoilage. The animal feeder is also configured to feed only specific animals. In particular, the animal feeder may include a support system with a pivot for supporting the feed container above ground level and enabling the feed container to rotate relative to the pivot, thereby preventing smaller species animals from feeding in the feed trough in favor of larger species animals. If a smaller species animal attempts to jump and place its front legs on the feeder to feed from the feed trough, the feeder spins causing the smaller species animal to fall back to the ground.
