I'm a sissy..i would just toss them all. Lord knows how long they have been sitting around. But thats just my opinion... many folks do the float test and it works.
I float test when I lose track of who's what is where. Works great! I use a plastic dishpan, cuts down on breakage. Then I sort them into cartons and put the older ones in the topmost carton, to be used first.
when in doubt, I make a HUGE batch of scrambled eggs and the chickens and dogs get a yummy treat. We call it "recycling" turn your old eggs into new eggs!
I would candle them first. Carefully. If there is dark stuff that sloshes around in there, carefully throw it as far away as you can. Then if there is a chance that they are fertile, you can see if they started developing. If you plan to eat them, I would candle again a few days later to look for blood rings from any in the early stages of development. Eggs for my personal use aren't always refrigerated, and I have had them sitting on a counter for over a week at times. I wash them right before use and do a float test while I am at it.
