What are the allowable variations on temperature of stored eggs being prepared for incubation before embryonic death occurs?

I believe they should not be left in the fridge, but am unsure on that one. Room temperature should be fine.

I am aware that 55 degrees is the optimal temp but how much variation from that can occur before there is embryonic death or defect?

I keep mine in a basket on the counter at room temperature (about 70F) and turn them daily.
SO FAR when hatching the ratio has been very good.

I try to keep the temperature as close to 55F as possible and not to vary by more than 5 degrees either way. At 70F or over there is a risk of embryo growth starting.This would not always lead to the death of the chick during incubation but can give weak chicks.

sounds easy enough but how cold is too cold? i was also wondering if the eggs were layed in the morning and not collected till the afternoon would the cold temp outside have any effect on hatch rate?

Nate:
Optimal egg storage temp it 50-55F for 7 days. Anything above 68F can result in slow development beginning which can be detrimental and result in poor hatch rate. Eggs freeze at 28F, however I would think that keeping eggs much under 35F for any length of time could be harmful. "A Guide to Better Hatching" recommends storage temp between 40-60F.
As far as collecting everyday, if your temperatures are in the freezing range, eggs should be collected as often as possible, then you have a chance to save some eggs at least. If temps are above 40F you should be OK. Eggs should also be collected frequently in extreme heat.

My biology teacher hatched eggs I gave him after a few were in the refridgerator overnight. They hatched fine but the only reason they were in the fridge was because the chickens didn't lay as well as I expected that day and he wanted a full incubator so I pulled a few eggs out of storage. I think it is best to keep eggs in a slightly cooler room, just so they don't start developing on their own in a warm room. If they did start developing and couldn't maintain warmth the embryos would die, but if the room is just a bit cooler the eggs never start to develop and are able to stay for a few days.
