Abstract: An egg incubating tray has its egg cells arranged in a manner so that a large number of egg cells are located on each tray. The egg cells are arranged in a diagonal pattern of parallel rows, each row being offset from the rows of each side of it. The two sides of each tray parallel to the rows thereof are straight whereas the other two are jagged, conforming to the layout of the projecting arrangement of the egg cells. This arrangement permits egg trays to intermesh when trays are placed together with their rows colinear so that the projecting cells of one tray fit into the spaces between the projecting cells of the other tray. Each cell may be surrounded by upwardly disposed, tapered projections. These projections are positioned to hold the eggs, separate one egg from another and also to act as a shock absorber so that the eggs are less subject to breakage. Horizontally disposed projections may also be positioned in each cell, extending inwardly from a side of the egg cell.
