I live in Iowa so there are LOTS of corn cobs lying around in the fields after harvest just waiting to be eaten by deer. Since I have chickens and a good relationship with my neighboring farmers I just go out and gather corn off the ground, bring it inside and hand shell them. Its good exercise to gather the corn and shelling by hand just feels good. So, now, we have a bunch of kernels that we can mix in with other ingredients. Problem is we don't have a grain mill and for crying out loud the chickens don't want corn flour anyway! All we want to do is crush the corn. Are there any alternatives to buying a mill? (And, no, the days when you could take grain to an elevator and have them grind a few bushels are over, my friend.) And given that these birds have these incredibly muscular built in mills called gizzards complete with grinding stones, is it even necessary to cush it for them?
