Abstract: A plurality of wheeled multi-compartmented poultry containers or carts designed to be utilized in conjunction with a fifth wheel trailer which may be hauled by either a pickup truck or a tractor. The side frames of the trailer are comprised of hinged U-shaped rails or channels which serve to guide the wheeled poultry containers onto and off of the trailer bed. The system features the ability to easily manipulate the wheeled carts into the poultry house, load same with poultry, and then easily roll the carts back onto the trailer for transporting, without the need for auxiliary loading equipment.
