To go bad, it has to undergo processes which make it go bad. For most food, the primary ones are consumption by microbes—bacteria or yeast, typically. Eggs are pretty good at keeping these out.
I’ve heard that as an egg sits, the yolk slowly descends and as soon as the yolk sits against the shell, it’ll go bad. If you keep turning the eggs every week or so, they’ll keep for months even at room temperature. I’ve never tested this, but someone I know found that eggs could last at least 8 weeks this way.
This is the Mother Earth News study that often comes up on Google that fertile eggs, and possibly infertile eggs, could keep as long as 7 months if you refrigerate them and don’t wash off their natural coating.
An egg has to be able to stay fresh while a chick is developing in it.-- about 3 weeks, and the hen will be keeping it quite warm.
It’s amazing that something which isn’t alive, and is full of fat and protein and water doesn’t go bad in that time.
