Great article! I got my own ongoing experiment re: How long will a fresh bloom-intact egg will last unrefridgerated. The birds and eggs are kept in unheated basement. Birds are let outside to free range, are provided a healthy layer feed and typical scratch. Yes, their yolks are much darker than store bought and taste SO much better.
We have 1 hen (more a pet that just happens to poop breakfast) named Omelet. This fall we gently took in another stray hen who we named Betty. They are watched over by our big tough sweety of a rooster named Bob. Both hens have resumed laying recently after taking a break for couple months.
Now we have more eggs than we can eat...and we're not big egg eaters to begin with. We just liked the chickens. And the disabled gentleman I care for adores them Caring for the beasties is a good activity for him.
We have never washed our eggs and always leave the bloom on. Rarely refrigerate them. As I write this I have 4 dozen unwashed eggs sitting in my basement some of which have been down there for months since last summer. I'm waiting to see how long it takes for them to go bad if they ever do.
I just now broke open a couple eggs out of each carton and I actually think they're still good. The very old ones the yolks have thickened some but otherwise I'm confident if I hard boiled them they'd be fine. The "newer" eggs are unffected by all the time gone by.
Chickens are remarkable creatures! Best critters to have around for a reliable food source and eggs have an awesome shelf life.
My opinion, don't ever wash until ready to cook. Leave the bloom on, kerp them in a cool place and they'll last a good long time.
Would like to hear from others who have kept unwashed, bloom-intact eggs for a long while and if their older eggs proved to still be edibible.
Thx! I love this site!
