We rarely get an egg with poop on it, but if so, I cook it for the hens. I don't wash the eggs we eat, but I am careful how I crack them. Following Jacque Pepin's advice, I don't crack them on the edge of a bowl or pan, but on a flat surface. This way the outside of the egg doesn't get forced inside. I wash my hands after handling every egg just like I wash them after handling the chickens or their feeders and waterers.
