That's an interesting idea. Probably too late for the OP to source this, but one could ask a local farmer to set aside a couple dozen eggs and never refrigerate them, then they'll last longer for the camping trip.
In Europe, eggs are on the shelf - as in, not in the fridge.
Once eggs have been refrigerated, they should stay that way. But if they've never been refrigerated, they'll stay fresh - I think a couple weeks? Certainly a week for sure.
If you think about it, eggs are supposed to stay fresh for a while. You have a hen and she'll lay a fertilized egg and it will sit there. A day or two later she lays another. And so on. Then she gets broody and sits on the eggs. That first egg is still "good," it's not rotting yet. When she broods the eggs will be "activated" all at once and start to gestate. Then all chicks will hatch the same day, despite each egg technically being of a different age. Long way of saying that eggs are meant to stay fresh for a while without refrigeration.
