As someone who raises chickens for eggs on our hobby farm and have done much research surrounding this, having been raised in the U.K. and now living in Canada I have the following info: In North America, I cannot speak to the quality of the conditions in which the eggs are laid, but they are washed. The Health Department requires that washed eggs be refrigerated due to the removal of the cuticle or "bloom". In the supermarket, eggs are refrigerated accordingly and they should be refrigerated at home too. In the U.K. the eggs don't undergo any process that removes the cuticle and thus they're not refrigerated in the supermarket and thus don't need to be refrigerated at home. When I pick the eggs from our free as in "can come and go as they please" chickens in the morning, some of the eggs I have been stepped all over by careless chickens with dirty feet and thus I like to wash those eggs and they can either then be dipped in mineral oil to mitigate the need for immediate refrigeration or as I frequently do, I put them in the fridge after I wash them. If the eggs are clean, I don't wash them and leave them on the counter where I treat them as good for 2-3 weeks without a second thought. Of course, if I were selling these eggs, which sometimes I do, it's usually less of a ball ache my explaining why they don't need refrigeration than it is just to wash them and tell people just to keep them in the fridge as normal - unless they want the whole "farm fresh organic treated like wild chickens" experience, in which case I tell them to keep them on the counter in a little wicker hay lined basket for that farmhouse vibe... and eat them up within a week... because that way they'll buy more.
