    Not sure if your egg is a freshly laid one or if it's been hiding in the coop for weeks?

    These floating eggs are not fresh.

    Follow these simple steps:
    1. Get an egg.
    2. Fill a cup with water.
    3. Place the egg in the cup of water.
    4. Observe the egg.

    Floating egg = Not Good

    Good eggs will sink to the bottom.

    Fresh Egg Laid Today:

    As the egg gets older it loses moisture through the porous shell and as a result the air cell grows bigger. The bigger the air cell, the more floaty the egg. So this is an indication of how old the egg is. It doesn't mean an egg that sinks to the bottom is a "good" egg though! Trust me I learned that one the hard way. It's only an indication of freshness/age of the egg.

    Eggs that float can also sometimes be quite fine to eat, just a bit… well, not fresh any more.

    Note: When in doubt just crack the egg in a separate dish.
    If you are really in doubt crack the egg in a dish OUTSIDE!

    Had given my daughter a dozen of free range eggs from my flock. Mind you, she not the cooking type, but does try her best. Unfortunately two months later she called asking if the eggs are still eatable. I never knew how to tell between a good or bad. She researched it and said the exact information you just stated, but with pictures.

    You have done an excellent job in providing a simple knowledge that not all knows. Thank you.

    Before I got my own flock and was buying commercial eggs I had noticed for years that bought eggs floated when trying to boil them. I remember when I was young the commercial eggs sunk in the water, and was so egg cited when I had really fresh backyard chickens to see - once again the eggs sink :)

    Thanks for sharing your article.
