i used to not wash them, but my hens tend to leave them a mess. i store them unwashed until i plan on giving them away. then i use warm water. and a scotchbrite pad. it seems that people are more concerned with the messy eggs than with the potential for bacteria. i tried to educate a few people on the "bloom", but they just looked at me weird. i do not wash the eggs that i save for myself.
It's a very rare occasion when I get a poopy egg. Sometimes in the winter, when it's really been raining, they get a bit muddy from hens crawling in and out of the nest. I just try to collect them a bit more often. Keeping your hens from sleeping in the boxes and refreshing the nest material often and you get clean eggs 99% of the time.
thanks for confirming what I have read. My eggs have been very clean so far. It's funny my mom used store our farm fresh eggs in a basket on the cupboard too. Most of us have become too citified. (I think that's a word) Raising chickens is bringing me back to my roots. A very good feeling.
