Yesterday I ate eggs that I put in the fridge, unwashed, in late April. They had a bit more air in them but were totally fine.I don't think unwashed eggs would last 2 years, nor 9 months. I've never had unwashed eggs over 4 weeks old.
My very fresh eggs are for making things that need egg whites, like Italian meringue buttercream. Or any baking recipe. Fresh eggs have a better albumen consistency since none of the water has evaporated.
Older eggs are great for boiling, there's room in the egg where the moisture has evaporated so they are less likely to crack while cooking. 3 month old eggs is a little excessive, but I try to use eggs that are at least 6 weeks old.
I've boiled eggs that floated the whole time, they were totally fine.
I do not use the float test for determining "bad eggs". But my eggs are not fertilized so I'm less worried about them spoiling. Eggs you get from the store are usually at least a month old already. So I'm not super worried about getting sick unless it's an egg covered in poo. Those get sent to the compost or washed, scrambled and fed to the dogs.
I do freeze raw scrambled eggs for camping, but now that I have A freeze dryer, I'll be putting up eggs for long storage that way instead.
