Got a Good Grain Recipe

[shipahoy41]

I found this grain recipe for my African Nightcrawlers.Makes them fat and with some vegtable peels pretty healthy also.
2 cups oatmeal
1cup cornmeal
12 eggshells can be off hardboiled or raw eggs
Throw it all in a blender or food processer and grind it up like a powder.Or just put it in a zip lock bag and crush it up with a rolling pin.Sprinkle it on the surface of the bed every day or two.You'll see when it is gone to feed them.

I will have to add the oatmeal and crushed eggshells to my Red Worms as soon as I go get some more. What do the egg shells do? Just curious. Thanks
