ABSTRACT:
An egg tray is provided which holds the eggs at an angle of approximately 35.degree. relative to the horizontal floor of the tray with the large or air-cell end of the egg being elevated. Air vents in the tray sides permit fresh air to flow directly over the eggs during incubation. A hatchery facility includes racks for holding a plurality of such trays loaded with eggs. The loaded racks are rolled into an incubation and hatching chamber through a first set of doors which connect the chamber to a first hallway in which fresh air is circulated. After incubation and hatching, the racks and an air control unit in each chamber are removed through a second set of doors into a second hallway in which air from the chambers is vented during incubation and hatching. The air pressure in the first hallway is greater than that in the second hallway thereby minimizing the risk of contamination.
