Double shell?

[The Tiny Homestead]

I found this in the nest box along with the other eggs. There was more, but I peeled some off to investigate. Has anyone experienced this before? When I cracked it open, there is nothing out of the ordinary

Hi!

Sometimes eggs get a double coat of shell if it stays in the shell area too long.

Was there a damp spot in the nest or anything? That to me looks more like another egg was broken and the shell from it glued itself to this egg.

At first I didnt notice, but, Yes, there was a wet spot.. That was my first thought, but it seemed like such a perfect fit, I couldn't imagine that being the case.
I was a little worried about where the missing part of the shell went, but all the birds acted fine and they all laid an egg today. I was picturing yesterday that a hen dropped her egg on another one in the nest and broke it, hers slide perfectly inside the other one, pushing the wbite and yolk out, and the two became as one.
Makes me wonder what the actual scenario was.

Close! I picture a broken one in the nest already having it's insides eaten (happy accident) and a fresh one gets dropped in whole.. hence the debris between the two shells with the outer one being fully cracked and mostly missing but also not the same color as the inner one.

Double shelled eggs or whole eggs inside another egg are possible though..

I found one last week and this one this morning on the ground. Looks like an alien! I feel sorry for the hen that had to lay it. Must of hurt!
