Wash the poop off under warm water. Some of the bloom will wash away, but probably not all. But you really should refrigerate these eggs unless you plan to use them within a week. You can always drag them back out of the refrigerator a day or so prior to using them.
Have you looked at your nests and the hens in them to determine why the eggs are so poopy? Once in a while, a hen has poop still left in the cloaca as the egg is being laid, but more often, it's a poopy butt that transfers the poop onto the egg as it's being popped out. You can fix this by frequent butt washes. Just back a poopy butt up to a basin, splash water onto the poopy feathers to soften the poop, then rinse. Sometimes baby shampoo or body wash can gently remove stubborn poop, then rinse well.
The most common cause of poopy eggs, though, is nest sleeping. This deposits poop in the nests and eggs will get very dirty from it. This is very bad on a number of fronts, but the worst is bacteria can travel up the oviduct from the vent and cause serious infection, and it goes without saying that poopy eggs are something no one wants. If this is what's causing your poopy eggs, block off the nests after the hens have finished laying for the day.
