Some earlier threads have correctly referred to speeded development and
metabolism at higher temperatures. The charts for annual eggs show more
time required to hatch at lower temperatures than at higher temps. Could
this be helpful to the Species Maintenance program?
My question would be how low can you go on temperature of eggs without
causing developmental problems? If you could slow an egg's time to hatch
from three months to make it a year, you would have essentially insurance in
the bank. While we are very impatient to hatch eggs, might it not be better
when we lose breeders to have a year to wait before we wet the eggs? For
that matter, could the fertilized eggs or unfertilized eggs + sperm be
cryogenically frozen for later use? I would think the latter to be
exspensive, but it would certainly be a way to insure an egg supply.
Back to colder egg keeping. Has anyone tried to keep eggs for an
extended period at 50 degrees, 60 degrees? Do you still get a normal hatch,
and how long can you keep them? If you could keep the eggs for a long
period of time, you would be able to breed fewer generations over time and
thus keep closer to the original gene pool. Food for thought.
