The temperature and relative humidity of
storage, as well as the gaseous environment, interact
with the fertile egg over time during storage in such a
way as to affect the success of incubation either
negatively or positively. This interaction occurs both
above and below the “physiological zero”, at which
embryonic metabolism is minimal. This interaction
below physiological zero implies that certain physical
aspects of the egg must be affected by the environmental
conditions. As the eggshell is a relatively fixed component,
changes in albumen, shell membranes, cuticle,
yolk, or embryo proper must account for these time- and
environment-related effects. It is concluded that the
major contributor is the albumen, as it is obviously the
most dynamic component below physiological zero and
is strategically positioned.
