The way that you can tell if a egg is still good.put water in a deep bowl place one egg at a time in the water if the egg float to the top of the water the egg is rotten. If the egg stays at the bottom and one end floats the egg is good. And if the egg stays at the bottom on it side it is good
Most eggs have expired but normally you will know if its rotten
It's not safe for the eggs!
If it's not rotten? Eat it.
