how long is an egg fresh?

We have been waiting for our chickens to start laying and it seemed to be taking a while for some of them. Well that is because a whole bunch of them have been laying in an empty pot outside their pen! My cousin just came in with a good dozen of them!
So my question is how long does an egg stay fresh enough to eat when it's left outside? I cracked a couple and they seem fine. I can't find an expiration date on a single one!
Thanks,
Karen

 

Can you believe its been in the low 90's this week? That was the main worry. My cousin keeps telling me " it's FOOD, we cant throw them out". I think he's feeling sentimental, he loves those birds!
Like I said, I cracked two and they seemed fine, I have 18 chickens and three lay in the coop. A few probably aren't laying yet, so 12 could stack up in a couple of days easily in that pot if 6 or 8 chickens were to use the same spot.
This is new to me, the most chickens I have had is three, and they laid in a tree stump!

Thanks for your quick reply hfs, I appreciate it!

Thanks for all of your responses, this site and you guys are awesome! Cousin just ate some and seems fine, the eggs looked ok but I'm afraid. I think I may feed the rest to the pigs! Do I want the chickens to get a taste for eggs?
