Coffee Grinder

[Three Stents]

Anyone use a coffee grinder to turn egg shells into small pieces/powder?

I have, and mixed the powder into wetted chicken feed to give the chickens extra calcium when needed.

I sometimes give egg shells a smack against a fence post, or between the ground and my foot, when I chuck them out for the chickens. Sometimes don't even bother with that. It really doesn't need to be a complicated process where you wash them and dry them and grind them up.
