The yolk, being less dense than the white, has a tendency to rise to the top, gradually forcing aside the albumen above it, and, if allowed to remain for a long time in one position, the thin layer of albumen dries and the germ becomes glued to the shell.The chalazae to which the yolk is attached, being the densest part of the egg, counteracts this upward force by tending to drag the yolk down.The effects of storing and incubating eggs pointed end up:In the event that an egg is placed small end up, the chances are greater that an embryo will situate its head in the small end of the egg. Eggs cannot survive for more than 2 to 3 hours in extreme cold without external warmth from the hen. The egg's weight must decrease by 12% during incubation if good hatches are expected.

Fresh eggs up to five days old can remain at a temperature in the low 60s. A thermometer with a split or gapped mercury column will not give an accurate reading, discard it. If they're kept in ideal conditions, some authors - Gail Dammerow, for example(1)- considers it possible that they will remain viable for up to three weeks.
