I provide oyster shell, but after the initial "gobble up" of the first pound I bought (50 cents at the local feed store), they rarely touch it anymore. I also feed them back their own shells. I just rinse the shells really well (no slime left) and let them dry for a day or two. Then, I pulverize the shells in my mortar & pestle and combine it with the yogurt they get. They all love it! Once it gets cold, I'll be mixing shells, red pepper flakes, & yogurt into a good helping of oatmeal for the girls in the mornings (3 hens, they get about 1/2 cup and are golden).
As for feeding egg shells back though...I wouldn't suggest "tossing it in the nest boxes"...they might figure out where that "yummy calcium" is coming from!
