I read this here at byc, and have been doing it ever since. After collecting the eggs, I wash my hands and dry them with one paper towel. I then use that damp paper towel to wipe the eggs of any dirt before putting them in the fridge.
I felt weird eating the eggs for the first couple of weeks. I could only hold them in my hands and marvel at them! Everyone thought I was crazy. But after a while, the novelty wore off and now I eat them every day.
Re washing them...I've read in enough reference books that if you absolutely need to wash some poop off them to use warm (not cold) water and a soft cloth. If you end up washing most or all of the egg shell, the bloom will be gone and so will the natural bacterial protectant on the shell. To replace it, use a small dab of coconut oil to replace the bloom and place in the fridge immediately.
