Eggs, I found, are pretty durable, after 6 years of having chickens, i have had only two bad eggs, i do not collect them everyday either. I have a nest box but they currently dont like it, they mostly make a nest somewhere in the “foresty” part of the backyard. I sometimes find nests with up to 24 eggs and temps here are hot all year. I researched a couple years ago after I found a large nest sitting for weeks in 120 degrees (In the shade of course) and read That all the eggs have a bloom on them Which protects them and keep them fresh. Eggs you buy in the store have it already washed off. I cracked all the eggs before I cooked them and found not one of them was bad. Hate to be the contrarian here but looks like lots of you are throwing away good eggs. If you crack them and they look fine and do not smell bad, then they are good.
