However, if they sink, but stand on one end at the bottom of the glass or bowl they are not as fresh but still edible. Floating is indeed a sign of less-than-fresh Eggs, but the size of the air pocket is determined by evaporation of moisture from the egg. Evaporation isn't desirable but it's not the same as spoilage. Thus of course if any Egg float to the top they shouldn't be eaten.
