Here's some trivia for you. A hen only requires 25 hours to produce an egg. As hard as the shell seems, it has up to 17,000 tiny pores on its surface. Through them the eggs can absorb flavors and odors. That is why we should keep them in their cartons and store them that way.
Eggs keep fresh longer in the refrigerator.
One day in the fridge would be equal to one week at room temperature. You can tell if an egg is raw or hard cooked by spinning it. Raw eggs wobble. Contrary to rumor, you can't tell if an egg is fresh by dropping it in salt water. However, if you spill one on the floor, sprinkling it with salt is the best way to get it up.
