An apparatus for automatically handling palletized poultry coops containing live birds to empty the birds from the coops for hanging. A pallet loaded with tiers of poultry coops after removal from the livehaul truck by a forklift is placed on a conveyor to move automatically to the input end of a coop infeed conveyor extending transverse to the pallet conveyor. Upon alignment of the pallet with the coop infeed conveyor, a limit switch stops the pallet conveyor and an extractor is actuated which pushes a tier of coops off the pallet and onto the coop infeed conveyor. The tier of coops is moved along to an unstacker comprising a lay-down unit having a rotor with coop support arms arranged in quadrature such that the coops are laid down on an inclined conveyor with each quarter of a revolution. The inclined conveyor moves each of the coops in succession to a dumping unit that empties the coop. Each empty coop is urged from the dumping unit onto a conveyor and taken thereby to an inverter which turns the coop topside-up. Inverted coops drop down a slide and are transported by a belt conveyor to a restack rotor. After several coops are in position, the coops are set upright by the rotor into a stacked tier on an outfeed coop conveyor. The tier of empty coops is moved out toward the pallet conveyor and are loaded onto a pallet. After the pallet is filled with empty coops, the pallet is returned to the livehaul truck by a forklift.
