Stackable poultry container (10, 110) systems are described herein along with methods of using the systems in connection with the care of poultry. The stackable poultry container (10, 110) systems described herein may include feeder apparatus (130, 30) that allow for the distribution of feed to all of the containers within a stack of containers through the feeder apparatus (130, 30) provided in the uppermost container (10) in the stack. The stackable poultry container (10, 110) systems described herein may include a floor (120, 20, 220) that has waste apertures (150, 50) formed therein to allow waste from animals located in the container (10) to fall through the floor (120, 20, 220) to improve sanitation for the animals located in the container (10) system. The stacks of poultry containers (10, 110) may include waste shields located beneath each floor (120, 20, 220) such that waste falling through the floor (120, 20, 220) of a container (10) does not pass into the container (10) located below when the containers are stacked on top of each other.
