hey--eggshells are fine for the compost pile--SUPER, in fact, for your soil. Many places are deficient in calcium, and they are wonderful. However, I would try to find a better use for the insides. The suggestion of feeding them to the chickens is great. The food bank is even better. Or--you could try making a quiche or angel food cake??? (mmmmmm) or how about making those items and giving them away/selling them?
just a suggestion. =]
