How long can an egg sit in a coop unrefrigerated?

[jenposton]

It's been super rainy so it's been 2 and a half days since I made it out to our coop. I went out today to refill the food and water and found our first egg! Yay! But I have no idea how long it's been there. It wasn't there late Monday night but it was there today (Thursday).

How long can an egg safely sit in the coop before needing to be refrigerated? If it matters, we aren't "runny yolk" people. The egg would either be scrambled or baked in something, so it would be cooked "well done".

Toss or keep this one?

I don't refrigerate eggs I keep them in a cupboard, I would crack it and see what I thought, if it looks and smells ok then I would eat it
