Dried aggs have been a survival/camping staple for a long time, and are available on amazon

each #10 can contains the equivalent of 85 eggs.

Alternatively, a recipe for 1000 year old eggs:
"Thousand Year Old Eggs" are really only about 100 days old.

Duck eggs are used instead of chicken eggs.

The raw eggs are buried in the ground in a mixture of clay, lime, salt, tea and straw. I have seen recipes calling for pine ash instead of clay.

This mixture leaches into the shell and egg, making the interior smooth and creamy—like a ripe avocado in texture.

The yolk turns a vivid green and the white various shades of yellow, blue and green. It has been compared to the colors of a black opal.

To eat them, wash the eggs clean, shell them and slice into quarters. The flavor is rich, pungent and cheese-like.

I have not looked for them specifically but am told that you can buy these eggs in American Chinese markets where they are called Pine Flower Eggs.
