Are these eggs fresh or not?

It means you put ALOT of salt in there, just like the ocean everything floats in salt water, freshness has nothing to do with it

When you add salt to the water and put eggs in there, they will float anyways. Adding salt to the water makes things float easier. They could be fresh or not fresh. Hope that helps.

whenever eggs become older, the air chamber becomes bigger. so, if you put eggs in salted water and they float, they are not very fresh anymore. does not mean, they're rotten. the question for me is: why put salt in water to cook them? add a little vinegar to the boiling water. so when they crack during the boiling the egg white will coagulate and closes up the crack.

They're not there. Sigh............

And you put too much salt in the water, why are you boiling eggs in salted water. By the way, you want to boil eggs that are not so fresh.

The membrane around an egg separates from the shell at the top/tip of the egg as it ages. The bigger the pocket at the top off the egg the older it is.

You would have to use a box of salt to create buoyancy.

Vinegar is what makes the eggs peel easier.

The older the egg the easier it peels.

If they are "floating" they are not very fresh they can jiggle a little when boil ling but not float on top

It sounds useful. yet actually i've got in no way heard of any controversy approximately used egg cartons. i purchase my eggs from a neighboring farm and that i'm getting used cartons (I return the cartons whilst i purchase greater eggs). The eggs i purchase have been washed, so i do no longer challenge approximately that. If I have been given eggs which regarded unclean, i might wash them and not could rigidity approximately an infection. There are not any doubt people who might like (even call for) new cartons...and little question human beings like me, who do no longer challenge. So, perhaps you ought to offer eggs in a sparkling carton for $2.25, and eggs in a recycled carton for $2.00. stable success, I desire I lived close to sufficient to purchase your eggs. i might.

a fresh egg floats in fresh( unsalted) cold water

If floating, they may have a crack which allowed air in.
