“Last”. Yes. In practice, I found eggs in a fridge age by weeks. I would still call them “fresh” within a week. After that, they don’t taste as well. Another week after that, visual changes happen on the shell. I can see as if the fluid inside is “breaching” the membrane thus dark spots on the outside. This is the last stage I would still be willing to consume them. After that I would throw them away.
