What do you feed them? They maybe suffering from low calcium. or what do you but in the nest boxes?

Can you share a picture of what you are seeing?

Your hens may be at fault, but you may also have an unexpected visitor. When I hear crushed eggshells, I'm envisioning this (https://www.instagram.com/p/CDR8EpzDYze/) which is what a skunk was leaving us after visiting our coop.

If you are just seeing cracks or holes in the eggs, that may be your hens. I find this happens with clumsy hens who step on their eggs. Hens that are eating eggs will generally not leave anything behind.
