Calcium deposits on and inside eggs

[GibsonFamilyFarm]

Hello!
I have 4 Ameraucana hens I purchased as TSC last May. They have been laying for a little while now but all 4 of them have eggs with calcium deposits on and even one has them inside.
One of the 4 was on a layer feed for a while and still had the same issue. Oyster shell is offered as well.
I’ve never had an issue like this that has lasted so long. Every one and then I would get an egg like that from a hen, but not daily. The eggs with the most deposits are always thinner.
My best guess is that it’s genetic? Hoping to find a possible solution or answer. Thank you!

Thank you.
Unfortunately it doesn’t answer my questions. Most of what I have read says that it’s fine and should resolve itself unless they are sick.
Since they are all from the same hatchery and same place, I’m assuming it’s an issue from the hatchery. My hope is when they turn one that things will even out.

Probably.
Doubt there's a solution.

I have the same issue with my Easter egger along with her having a poopy butt that we can't seem to clear
