I have only had chickens for 3 weeks, but have already got over 6 dozen eggs from my 6 hens. I don't plan on selling any, but have given some away to friends and family. After gathering the eggs, I gently rub them with my hands under lukewarm running water and dry them with a paper towel before putting them in the fridge. I have a mix of straw and wood shavings in my nesting boxes and rarely have anything on the eggs other than a little bit of saw dust anyway.
