Well after reading 4 different threads on this , as usual there is conflicting advice. The one that made the most sense to me is if you aren't going to refrigerate than DON'T wash as it will protect it at room temperature and last longer than it would without. But as someone pointed out one day on the counter = 1 week in the fridge, so if keeping them on the counter, even without washing, you have to plan on using them soon.
If you refrigerate them you SHOULD wash them as the cold from the fridge will open up the pores anyway and let in any dirt/poo on the shell. But the cold will keep the egg fresh longer in the long run.
Just some things I read. Mine just started laying , and so far they lay really clean eggs ,so personally I'm giving them a warm rinse and then refrigerating them. Right now I'm only getting a few, so I can use them pretty quickly
