So I picked up a bag of chick grit today when I was getting some more crumbles. I didn't think anything of it, the bag said "Chick Grit Crushed Granite". I opened it up, and it's RED !!!! I looked at the ingredients, "Ground Granite, Anise, Red Color (Iron Oxide)". WTH?! Is that to make them peck at it more or something? I don't think I want to give it to them. I think the brand is "Nutri Source". Anyone used this before?
