Although eggs may seem quite solid, they are actually porous. The older an egg gets the more air enters the egg, and the larger that little air pocket at the end becomes. In a rotten egg, the air pocket gets so large that he egg floats, and the gasses inside become contaminated - which is why rotten eggs smell so bad.

Because as the egg decomposes, gas is formed making it float. Any good egg sinks because its a shell and a liquid center.

Eggs have an air sack at one end. As they age they lose moisture and this gets replaced with air which is lighter that water. So you find as they get older, they first raise one end and then stand vertically and then float. Or you could just add salt and make them all float.
