i pitch my egg shells into my garden. i don't crush them. i use the tiller in the spring...That looks like a good option. I made a grit and calcium feeder out of a couple of PVC pipes and elbows. Just fill it from the top and it autofeeds the grit and calcium as the chicken eat it. I have it mounted in the coop so the grit and calcium is available 24/7 as needed. I only have to refill it maybe every 2-3 months.
I have 10 chickens. I still have about half a bag of grit and calcium I purchased 3 years ago. It's not expensive, and lasts forever. My chickens also are outside most of the day (in the non snow months) so they can get grit from the ground, and I will save our egg shells, crush them up, and feed them back to the chickens.
