Method and apparatus for unloading poultry are disclosed. A chute (35) is placed proximate the door of a coop. The door is opened and the poultry are urged out of the coop onto the chute (35). The poultry then slide down the chute (35) onto a conveyor (11), (15) which ultimately transfers the poultry to a gas stun vessel (25). The poultry are then transferred to a shackle line where they are shackled, without a full lift, and then proceed to an electrical stun (72) and killer (73). The gas stun vessel (25) includes a static mixer (53) for effectively mixing the CO2 and air before delivery to the gas stun vessel (25).
