floating egg ????

That floating one probably isn't good, the others sound like they're on their way out as well

 

How long are eggs good for?

 

I found this when I first started on BYC:

Eggs are good when:

Fill a bowl with water deeper than an egg is long.
Place eggs in bowl.
If eggs settle to the bottom and lay on their side...they are as fresh as can be can be and yolks do not need to be thoroughly cooked.
If eggs, while still on the bottom of the bowl, start pivoting upward they are a little less fresh but can still be used for baking, scrambling, etc.
When completely upright but still on the bottom of the bowl...the egg is still ok but must be thoroughly cooked (scrambling, used in batter for frying, etc.)
Once the egg actually starts to float and is no longer in contact with the bottom of the bowl...toss it!

When things spoil, they oxidize; This might explain the whole floating egg method.

 

Myself, I'd toss the floater, and boil the almost floaters for chicken food.

 

I just walked out gathered 10 fresh eggs. (Gathered daily). Put them to boil, they ALL floated. I know for sure that they are fresh. So, I will say that it's not true.
