[5] found no effect
of preincubation storage on viability and hatchability
in young breeders and viability was
even higher in fresh eggs from older hens. Furthermore,
longer storage periods decreased embryonic
growth rate, viability, and hatchability
at all flock ages and was more pronounced in
older flocks [7, 13]. These conflicting reports
suggest that further studies are necessary to
determine the effects of storage and age of
breeders and their interaction on egg quality
and hatchability.
