An avian transport box device transports birds economically and allows a person to extend a hand through a perimeter wall of the device to extract birds while multiple devices are stacked. The device includes a perimeter wall coupled to and extending from a perimeter edge of a bottom wall defining an enclosure. A top wall coupled to the perimeter wall is positionable to cover the enclosure. Each of a plurality of apertures extends through the perimeter wall. An opening extends through the perimeter wall. A door pivotally coupled to the perimeter wall is positionable in the opening for preventing a bird from exiting the enclosure through the opening until the door is opened. A cover panel coupled to the top wall is positionable over the opening in the perimeter wall and the door while the top wall is covering the enclosure.
