I have young-ish hens laying lots of eggs for our consumption. With 17 hens I am getting between 12 and 15 eggs per day. About every day to every other day I get one egg with no shell on it being produced. My girls get high quality feed with enough protein, and I am also giving them calcium supplement and green leafy veggies and mealworms and other stuff to snack on. They seem fat and healthy. I am wondering if I just have one defective hen, or if they are still lacking in something in their diet. Today I got a soft-shelled egg with a tiny hard-shelled egg inside. Below is a photo of the tiny egg that was inside the clear egg. Next to a normal egg for size comparison.
