In the 1950s, I would visit relatives who had a 50 farm way out in the country. They had no electricity. They were really isolated. As they were elderly at the time of my visits, the farmland was unused. They had a few cows, several chicken, a few goats, and I can't remember what else. I do remember that they would store butter in the creek all year. I'm not sure what they wrapped it in. They would churn butter every few weeks, so I don't know why they would need to store any. They also had a root cellar. I'm pretty sure that I could not live like that. But they were in their 70s at the time and enjoyed their life.

When I was in Mexico all the eggs were in the aisles.
At the farmer's market a gal sells some eggs "dirty" with gunk on them...feathers and yuck. She says these eggs have never been washed so they don't need to be refrigerated. Once they're washed the outer protective coating is removed and the egg goes bad more quickly.
Oddly, I was buying some eggs from an Amish farm and they were lovely clean but I could leave them unrefrigerated. I don't know how they did it.
