Fresh eggs froze and burst, store eggs didn't freeze

We're in Northeast Georgia and had an ice storm last week. My mother-in-law was out of power for several days and stuck her eggs out on the back porch and the fresh eggs that we had given her froze and burst, the store eggs she had did not freeze. She broke them open to see what was going on and they were raw. Does anyone know why this might have happened?

Fresh eggs have not dehydrated yet. The air cell is very small allowing for very little expansion. Just like ice cubes in the freezer, a frozen egg expands and cracks the shell. The fresh egg cannot expand very much without cracking the shell due to the small air sac.

A store bought egg is potentially weeks and weeks old. The air sac has dehydrated, allowing the egg contents plenty of room to expand without cracking the shell.
