Hmmm... thanks for that info. I’ve never tested one that floats just assumed it was bad and I got rid of it. Will have to check that out from now on.
Floating just means it is an older egg, not always bad. Floaters need to be broken one at a time into a dish to check them though. If it looks fine, no odor, and the yolk stands up does not break or flatten when put in the dish it is ok. We did this with every egg though and didn’t bother to see if they floated or not because chickens can hide eggs on you so some you gather may not be as fresh as you think!
