Abstract: A feeder apparatus includes a feed hopper including front and rear end walls, a pair of opposed side walls each formed by upper and lower side panels secured together by a first plurality of removable fasteners, and a lid movable between open and closed positions. The side walls are attached to the front end wall by a second plurality of removable fasteners and to the rear end wall by a third plurality of removable fasteners. A feed tray assembly is secured between the front and rear end walls by a fourth plurality of removable fasteners. The feed tray assembly includes a tray and a pair of opposed side rails attached to the tray by a fifth plurality of removable fasteners. An axle assembly including an axle and a pair of opposed side mounting plates is attached to the hopper by several of the fifth plurality of removable fasteners so that the axle assembly may be added to or removed from the apparatus without requiring modification of the apparatus or further fasteners.
