If you have ever fed the animals at the zoo or the birds at the lake using coarse kernels from a vending machine, you have probably handled cracked corn. When dry corn kernels are ground up into cracked corn they make excellent animal food with a long shelf life. Any corn that is less than perfect for human consumption can be ground up into cracked corn and fed to chickens and cattle. Cracked corn is quick to make and easier to store than whole corn.
Remove the husks from the corn with a strong pulling motion. The husks can be peeled and discarded.
Cut the corn off the cob using a sharp knife until all of the kernels have been removed. Continue this process until corn has been removed from all of the cobs.
Place the corn kernels in a dehydrator and heat on high for six to twelve hours. The corn should be very dry and brittle when ready.
Place the dried kernels in the feed section of a coarse food mill. Avoid filling to the top of the feeder to keep the kernels from spilling over the top.
Slowly turn the handle of the food mill to grind up the dried kernels, producing cracked corn.
Continue to add more kernels to the mill until all of the corn has been cracked.
Place the cracked corn into a bag or sealed container for storage.
