If you didn't already know, a chicken's egg comes from the same opening as the poop! That's just the way it works, which is why eggs from your own chickens or even from a farmer's market will most likely have some poop stains. However, in the United States, each state has its own rules, and they may require that eggs be washed before being sold. Naturally, you don't want to store dirty eggs in the fridge or even on the counter. Instead of washing off any dirty eggs, carefully scrub them away with a rough cloth, paper towel, or your fingernail until you have clean eggs. This should get rid of the muck while preserving the bloom. However, very dirty eggs should be rinsed under warm water before refrigerating. If you have your own backyard chickens and feel that chicken poop is becoming a problem, clean your coop and nesting boxes more often, or collect eggs twice a day instead of once a day. The will surely turn your dirty coop into a happy chicken coop!
