I know that washing eggs removes the bloom, which protects the egg from bacterial infestation, but I sell them soon enough to prevent this. I understand that you should wash eggs if they're dirty, but what if I got them from the nest spotless? I know some people who never wash their eggs, and sell them when they're all dirty and full of poop and hay, and I think it's disgusting. But my coop is pretty clean, as are most of the eggs.
