Eggs have an air cell that becomes larger as the egg ages and acts as a buoyancy aid. An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. This means the egg is older, but it may be perfectly safe to use.
Are eggs bad if they float in boiling water?

This is not a myth; fresh eggs sink while bad eggs float to the top. Simply fill a bowl with cold tap water and place your eggs in it. If they sink to the bottom and lay flat on one side, they are fresh and good to eat. A bad egg will float because of the large air cell that forms at its base.
How do you know if an egg is bad when boiling?
Fill a bowl with water, and carefully place an egg on top. If the egg sinks like a stone, laying down on its side, it’s still very fresh! If it sinks but doesn’t lay flat — and instead it kind of stands up, wobbling — your egg is OK and probably just right for hard-boiling.
