The rule of thumb for time in storage is seven days. Eggs have been successfully kept for longer periods, but seven days is the longest you should plan to store your eggs. Hatchability chances decrease after the seven-day mark, due to vitamins decaying and the membrane breaking down.
How long can eggs go without being sat on?
With the concern about Salmonella, eggs gathered from laying hens should be refrigerated as soon as possible. After eggs are refrigerated, they need to stay that way.

How long can incubated eggs survive without heat?
Some embryos can survive at temperatures below 90°F for up to 18 hours, so do not give up. You should continue to incubate the eggs after the outage; then candle them 4 to 6 days later to see if there has been further development or signs of life.
What is the longest incubation period for eggs?
