I don't do expiration date on eggs. If they don't stink or have an off color, they're good to go. ;}
A little holiday egg trivia. Old eggs peel better than new eggs. I learned this while living in TN where one can actually get older eggs. I was amazed that eggs that had been left in the fridge for two weeks would easily make gorgeous deviled eggs.
Moved back to Texas... two month old eggs don't peel well. Eggs here are too damned fresh.
I actually knew that - My general use cackle-berries are free range and fresh, but I actually buy eggs to boil, because they peel better... and that dash of vinegar thing actually works to keep em from cracking in the boil too.
I eat a lot of pickles, so I always have a bunch of pickle juice around... Pickled eggs are awesome.
