Egg shells appear to be thinning

[Big Doggie]

I have 11 month old Golden Comet pullets who have been great egg layers all winter. They are on All Flock with a generous supply of oyster shells on the side. In the last month or so the shells for a few of them have been very thin. Not sure why.
Any suggestions?

You can crush up some egg shells, or throw them in a processor. Egg shells are calcium, but not grit. Don’t feed too much though

Are they eating the OS?
Mixing crushed egg shell in with the OS can help increase consumption.

Are you feeding any other foods or 'treats'?

Yeah they get a handful of mealworms when I want to keep them busy. That way I can open their coop and clean it out without the whole flock in the way of my slotted scoop.
My question is do they stop eating the oyster shell or eat less of it for any particular reason? There’s a generous supply.

Some bird aren't prone to eating the shell..gotta fool them into it.
I keep a few tablespoons in the feeder shown below.
I mix in crushed egg shells when I have them.
They don't eat it when not laying.

We have one out of 4 chickens that’s laying super thin eggs. Lately that egg is usually broken. Today I found it and can’t believe it’s not broken. It’s beyond thin. We give them oyster shells in their food and treats often. So odd.
