ABSTRACT:
An elongated teeter-totter feed trough with perches on its opposite ends has a central portion pivotally connected to a housing. The upper portion of the housing forms a hopper for bird feed. A mechanical linkage assembly interconnects the trough with upright feed shafts at opposite sides of the hopper. Rocking motion induced by birds landing on the end perches reciprocates the shafts relative to the housing. Each shaft has a cavity that passes a bottom outlet of the hopper as the shaft is moved. Particulate feed in the hopper fills the feed shaft cavities for carrying a measured quantity of feed from the hopper to chutes that dispense the feed to the trough.
