A portable feed is provided with a frame having a tow hitch, a plurality of wheels and a storage bin. The portable feeder can be towed from a feeder location to a refill station and refilled. A variably sloped floor extending through the storage bin and each feeder chute provides for the continuous flow of feed to the chutes for on demand feeding without substantial spillage from the open ends of the feeder chutes. A lower chute surface is pivotable relative to an upper chute surface so that the lower chute surface is movable relative to the upper chute surface in a clamshell-like closure.
