Are my chickens eating their eggs?

[JudyChickenNeighbor]

I have four 26 week old chickens. Two of them have started laying eggs for several weeks now. We were getting normal eggs but recently when I go to collect the eggs I noticed that both or one of them is crushed in the nesting box. Are the chickens eating their eggs or is something wrong (health wise) with the chickens and curing weak shells? I’m attaching some pictures.

What do you feed them; brand name, or feed analysis would be helpfull.
Sometimes new layers lay one or two imperfect eggs but given it seems this has been going on for several weeks and it's not specific to one hen (?) then a lack of Calcium in their diet would be my starting point.
It isn't deliberate egg eating I would think. Eggs breaking due to weak shells are fair game. It's when one finds a hen going at a pefectly good egg like a woodpecker one has to worry.

either some eggs aare cracked or have thin shells, or you do have egg eaters.

We feed them the Purina Layer Feed and Grub Terra as a snack. Sometimes we give them kitchen scraps like leftover vegetables, scrambled eggs, fruit. We also feed them back their eggshells and also provide them oyster shells on the side.

The two hens that are laying had perfect eggs in the beginning (about 1 month). Shells were super strong, laying one egg per day. However, just recently they are laying every other day or skips several days in a row. When we do get eggs they are crushed in the nesting box.

Any help/tips would be appreciated!!

Are you sure it's the same birds laying the thin shelled eggs, or could it be the others just starting to lay? In any case, I would be very surprised if it's deliberate egg eating this early in their lives. Teething troubles for new layers can be intermittent and continue for months. I would keep cleaning up and watching for a couple of weeks.
