ok..tyEliminate the scratch and mealworms. Scratch is extremely low in calcium and that dilution could have originated the problem.
Scratch, depending on the types of grains, could be 0.5% calcium or less. Mealworms contain a little more than 3 mg/100 grams. That means they have virtually none.
It is important to remember that the layer feed you are giving is complete, with all the nutrients they need in exactly the right ratios. They don't need treats.
Adding scratch and mealworms will screw that up and it is best when one has the problems you do, go back to basics - meaning feed only.
I refer again to the factors that affect shell quality.
