Egg Sandwich

Q: If you float an egg in warm water and it floats is it fertile? Or if you try and float an egg in warm water and
it sinks is it a dud, or is it the other way around?
CONFUSED!

A: If you float a fresh egg in freshwater, it will sink, whether it's fertile or not, because it is denser than water. The only difference between a fertile and an infertile egg is one tiny sperm cell. However, it would seem to me that as the embryo developed within the egg during incubation, the egg would lose some water and would be less dense over time and just might float - I've never tried this however. But testing recently laid eggs to determine their fertility status won't work with the float technique.
