How to Survive Prolonged Egg Storage?
Dr. Inge van Roovert-Reijrink M.Sc.
Storage of hatching eggs longer than 7 days causes a delay in hatch time and a decline in hatchability and chick quality. Hatchability declines with approximately 1% per day after 7 days of storage. The cause of this decline in hatchability and chick quality is not clear. During storage changes occur in the embryo. One of the changes is that cells in the embryo die. This can have a negative effect on embryo viability and consequently increases embryonic death.
