Thin eggshells

[Chicken.Lytle]

I am starting to have trouble with thin eggshells from one of my hens. I am attempting to cure it with yummy food since they don't seem very interested in oyster shells.

Any suggestions?

My hens have only been laying a couple of months or less, but their shells are as hard as rocks!

I have crushed baked eggshells and grannite grit, free choice all the time, I caught one of my girls baling out the eggshells because she only wanted those that had dried yolk on them.

But I leave a 8 -10 inch pottery clay bowl out in the run filled up with the stuff and I see them eating it all the time (visible from kitchen window) even when other food is available, so I guess they know how much they need.
