All my searching points to aging of eggs. Even in official documents.
A fresh egg will have a round yolk inside a thick egg white, encircled a thinner egg white.
An egg which has had time for air to enter the shell will have a flat yolk, and watery egg whites. The yolks walls will be so thin that it will break easily.
I brought in two eggs right off the nests, broke them in separate bowls, and let them sit all day. No breakage. Maybe we're overlooking the older eggs in the fridge. I don't know.
