White shell inside a brown shell

mysterious egg
I found a brown egg with shell partially pecked off, underneath is a hard white shell. I can understand the shell inside a shell but how is the egg both white and brown if the color is determined by breed?

All eggs are white, the brown is just the pigment on the outside of the egg. But when you crack it open you can see the the shell is actually white. There are certain breeds that lay true blue eggs as well.

Egg shells are either white or blue, depending on breed.
Brown is a coating and makes white shelled eggs brown and blue shelled eggs green.

Here it looks like the white egg didn't get coated and laid,
but instead 'backed up', got shelled again, then coated and laid.
It's not common, but not unprecedented.
