Are these eggs safe to eat?

Bad eggs float, good eggs sink, eggs 'on the turn' are somewhere in-between.

There is a small air pocket in the large end of the egg. When the egg is fresh, the pocket is only about 1/8th of an inch deep. As the egg ages, however, it loses both moisture and carbon dioxide — shrinking — so that the size of the air space increases. And the size of the air space determines the buoyancy of the egg.

So if you submerge a very fresh egg in water, it will lie on the bottom. An egg that is a week or so old will lie on the bottom but bob slightly. An egg that is three weeks or so old will balance on its small end, with the large end reaching for the sky. And a bad egg will float.

Sounds to me like yours are in the 'on the turn' category so isn't bad and is okay to eat.

An egg that fully floats in the water and does not touch the bottom of the bowl at all should be discarded, as it will most likely be bad.

That information can't be precise, a million gram of fats has 9 energy, so there could be ninety 9 energy of fats and 3 of protein. which potential there could be 3/4 of a gram of protein in that egg. As on your question, egg whites are fats loose, yet almost all the foodstuff you get from eggs are contained interior the yolk. Sodium is in almost each and every little thing.

The float test will only tell you which eggs are the freshest, not which ones are bad. The air pocket will get bigger as eggs age, because the shell is semi-permeable and allows air to get through into the egg. As the air pocket grows, the egg will float more.

The only way to really tell if an egg is bad is to crack it open and look at it, then smell it. If there is any hint of sulfur smell, the egg is bad. If not, go ahead and use it.

crack the big one into a cup on its own thats the only way to find out if its worring you they should be fine even if you bought them a week ago they still should be ok unless the farmer has had them for a week before they were sent to the shops then put them in deeper water if they do float take them back to were you bought them as they can go bad but it takes a lot longer than you have had them to go bad use them as normal if they don't float if you are going to eat them in an omlette you should use them as though you bought them today.

It says 'best if used by' which I always consider more 'lenient' than "expires_____". I often use eggs (and milk) several days to a week after the 'use by; date.

Oh yes, they will go several weeks after the sell by date. I've had them 1 1/2 months still were good.

I personally would have no problem using them.

of course they are!
