There really is not any benefit to removing the thin lining from the eggshells. There is a lot to be gained by smashing the eggshells up into as fine a pieces as possible though. It can take a very long time for them to break down into truly giving the full benefits to the compost pile and the gardens if left in large pieces. Breaking them down into very small pieces speeds up the break down process and gives you their full benefits far far quicker.
