Goose Eggs Hatching Delayed by Cooler Incubator
Charles W. Kossack and team studied natural goose incubation to compare temperatures with artificial hatching. Natural nest temperatures hovered near 100.4 F on the shell and about 101.3 F inside the embryo, yielding about 26 days to hatch versus 31 days in incubators set at 99.5 F upper surface and 93 F lower surface.
