There was a recent article on the web about the length of time one can store eggs to eat. The use by date on the carton is a few weeks off. Also the packing date is not the same as the date the egg was laid.
We store ours in the bottom of the fridge. They don't last very long there because we give them to family and friends. Sometimes ten dozen at a time may be found in our fridge. We have 25 hens and usually have better than ten eggs a day gathered.
We only wash the egg if it's soiled some how. We almost always have to
wash our duck eggs. Otherwise our hens are pretty good about keeping their nests pretty clean and neat. We have some milk crates with cardboard in the bottoms as well as straw for boxes and wooden boxes in the barn.
I have an old egg crate that belonged to my grandparents, that holds several dozen eggs. I recall they kept the crate in the cellar, with milk
cans as well, until it was full. They sold the eggs to a local grocery store. I recall the man at the store "candling" the eggs when they were delivered.
The cellar has fallen into disrepair over the years.
They sold the eggs to the grocery stores and a truck would come around once or twice a week and pick up the full "milk cans" and leave empties to be filled. They had a milk seperator to seperate the cream from the milk. The cream was put into a smaller can or made into butter. The grocery store would buy and butcher livestock, chickens included, for sale in their store. This was in the mid to late 50's.
