Abstract
A tray adapted to contain poultry eggs during both the incubation and hatching thereof, in a continuous operation not requiring removal or handling of the eggs between incubation and hatching, consisting of a tray body of sufficient depth to contain hatched chicks, its floor being divided into compartments each of a size to contain a single egg, loosely, lying on its side, said trays being adapted to be stacked to any desired height, and each tray having a removable cover capable of supporting each egg in a position with its major axis substantially vertical when the tray is inverted. Each egg is movable from its vertical-axis position, which is the incubation position in which development of the embryo occurs, to its horizontal-axis position, in which hatching occurs as the chick pecks its way out of the shell, by simply inverting the stack of trays.
