Do Eggs Need to be Refrigerated?
As an American living in Europe, I understand the horror associated with non-refrigerated eggs. 

However, I can assure you from my own experience, that if the eggs are fresh from a farm, unwashed, and stored in a cool location, they can last up to a month. (This is my preference, as the eggs taste far fresher.)

It is common practice here to find eggs simply sitting on the shelves of grocery stores without the benefits of refrigeration and the majority are unwashed eggs. I have used such eggs up to 10 days past the expiration date with no ill effects.

Best of luck.
