If you are not packing in your food (as in driving there), raw eggs in their unbroken, uncracked shells can keep for weeks. If you can get them straight from the farm, they may have the best chance to keep. Not all countries refrigerate eggs.

*I* happen to like Mountain House freeze-dried scrambled eggs, including the ones with peppers, etc., resembling a Denver omelette. I have been known to carry a portion in a cleaned chip bag, adding some instant potatoes, and keeping a catsup packet on the side.
