I was reading an article posted on the CDC about a recent outbreak of salmonella in some back yard chickens that were distributed in the Eastern U.S., in the article it states the following, I was kind of mind blown, it's all I've ever known and read, though I'm fairly new to this only had hens for four years.

How do you clean your eggs?

"If you are handling backyard poultry's eggs, the CDC recommends collecting eggs often, as allowing them to sit in a nest can cause them to break or get dirty. Any broken or cracked eggs should be thrown away. You can clean off any dirty eggs with a cloth, brush, or sandpaper—but never wash the eggs as the water can draw germs into the egg. "
