Refrigerated eggs are good for about four to five weeks after you buy them. As long as they are properly stored, you can still use them after the expiration date if it falls within this five week time frame.
Usually about a month. Sometimes the producers will say an exact date, but you can eat the eggs even after a week it is expired, at least that is what I do and I have never gotten sick from it.
0 seconds. Once something expires it is done for. Eating expired foods can present health risks and as such they should only be eaten in desperate situations of starvation (I will assume you aren't starving to death). I suggest you discard the food.
If your frugal I know how it feels, try to eat food before it expires in order to save money or do not buy as much next time.
Best before date always assumes you keep them refrigerated. However, the best before date is arbitrary so try the float test. Place the eggs in a large bowl and cover with water. If the eggs float at the surface do not use them, throw them away and do not break them (they will smell). If they are slightly bouyant then they will boil up fine or can be used in a recipe but not great for breakfast. If they stay under the water use them for whatever you wish.
Guinea and chicken eggs can not be refrigerated and stay fertile.
It will stay fresh for about 1 week depending on conditions such as temperature and humidity. To test for "freshness" use the float test. A fresh egg will remain at the bottom of a bowl of water while a stale or rotten egg will float. Eggs should be refrigerated as soon as possible after collection and can remain edible for many weeks when stored properly.
about a week
No more than a day
Until the egg hatches.
17 days for an egg to hatch out
yes are you stupid yes, but they last for a long if they are refrigerated. A spoiled egg will float in water.
Same as you would any other egg
i would drill a hole in one end of a watermelon. the watermelon will break and the egg should stay intact.
