Welcome to BYC. I hope you get the right answer to what is up with your weird eggshell. It looks like nothing I've seen before.

Hiya
Nice to meet you!

I would do some investigating around the vent of your hen. Those look like parasites eggs. I have a hen who will lay calcium deposits and if you compare the two photos you’ll see. Mine are in the shell. Yours are On the shell. Take a moment to check your girls over. Look for clusters of dusty-white crust on their feathers around the vent. If you find such a issue going on can start a new thread and we can help you. Best wishes
