For those of you making your own worm chow - unless it's a secret trademarked formula of course - I have a couple questions. 1) this is the chicken feed I bought. It's smaller than expected but I wonder if running it through the blender - or a grinder - would make it better because it would be even smaller for the little Vermi. 2) I've been using polenta (corn meal) & oats - both ground up with some egg shells - also ground fine. That's all I had at the time. Now I have the chicken feed but i'm not sure the best mix or what else I should look at adding. I'm not adding the eggshells anymore. It makes it smell icky, so I'll just add them separately. More questions to come!
