Is it possible to keep the egg of my humanoid character without hatching for centuries, but still able to hatch when proper care and the appropriate environment is provided? My planet is a extremely hot one, and my inhabitants are literally 'fireman'.
Here is some background information:
Without revealing too much, my humanoid race has an egg of another race (A bird-Human race). The thing, which will hatch from the egg will either be their saviour or Satan. So they could not just destroy it or allow it to hatch, instead they keep it in a frozen like state (Or in some state which will neither destroy the life in the egg nor let it develop - a stasis or sleep like stage I guess)
My race is highly developed in technology, so they can go to any extent to achieve the feat. After centuries, the egg is somehow returned to it own race members. So all I need to know is, whether it is possible for them to hatch that egg using their traditional method? It is something like the presence ,heat, care from the mother and some other factors.
