Fig. 1 shows a section and Fig. 2 a front view of the bin, which may be made of 3/4-in. pine. The sides are made with the grain of the wood running from top to bottom, a ledge being nailed across the lower and top edges to prevent warping. A A (Fig. 2) show the lower ledges, those at the top being inside. The front (A, Fig. 1) extends from the top to a little less than half the depth, and from this a piece of tin forms the front of the hopper and reaches to the feed-hole B (Fig. 1), which should be of such a height from the ground that the poultry can reach the grain. The feed-board is hinged to the back of the hopper at C, the joint being protected inside by a strip of canvas. A batten D is nailed across the grain of the feed-board to keep it from warping, and is extended through to the back, where a bolt with a thumbscrew is provided which may be turned to regulate the size of the feed-hole B to suit the size of the grains of corn that are being used. The sides are cut away in the centre at E to give a firmer bearing on the ground. A sloping roof is provided, fitted with hinges at the front and a hook and eye at the back.
