The bloom on the egg is a protective coating that keeps bacteria out. The eggs that need washing, use them up first.
Unwashed, eggs can be stored on the counter for a couple of weeks. Once washed, they must be refrigerated. Unwashed eggs can last up to 3 months in the fridge. Washed eggs will not last that long.
We live in a hot climate, we dont wash any of our eggs.
Never had a bad one, eaten or otherwise. Not even a slight smell after more than a month on the counter.
The ones that are sitting around more than 3 weeks dont have that fresh taste, they get a little stale kinda like bread. Its still good. Just like bread, its obvious which loaf was eaten quicly and which one was not.
I dont really support washing eggs or putting them in the fridge unless you have a very dirty coop or birds who habitually lay in their own poop zones.
If we get one that has poo on it (some foot love) we knock off what we can with a flick and let it dry.
When opened, just open from the side with no poop over a bowl and not over the food or pan.
If the terribly unlucky happens and the poo flakes off into the egg just feed it back to the chickens, they love it!
I dont really support fridge eggs either. Eggs need to breathe, they really do need that bloom on them so they can stay fresh and alive instead of cold and dead absorbing all the odd flavors and smells in the fridge. Plus if your fridge is anything like most peoples its not to clean and a bad place to put an egg after the protective coating was removed.
I find that eggs out on the counter (even with a speck o poo) unwashed will be fresher tasting much longer and last about as long as any washed egg even in the fridge.
So for the best results and flavor get them eggs every day and leave them in a cool, dry and dark place. Dont touch the natural barrier, but flick off anything that doesn't belong.
Healthy chickens make healthy eggs that just dont need to be messed with.
If the idea of poo on your eggs bothers you, then wash. However you really dont need to wash the egg even with a foot print on it, that bloom is resilient! Flick and dry, you'll survive I promise.
(remember that bloom is on there just for the purpose of poo protection. you really think wild chicken feet are clean when they turn that egg every day?)
That being said, every one has their own story and opinion.
Wash away if you just cant help it
