Egg storage longer than 7 d is associated with a delay in hatch time, and a decline in hatchability and chick quality. During egg storage, embryo viability declines due to an increase in cell death. Albumen quality, which affects the micro environment of the embryo, declines as well due to a rise in albumen pH and a decline in albumen viscosity. Whether the change in albumen quality affects embryo viability is unknown.
