I'd like to know what grit they are talking about. Kalmbach is a US company so it is probably insoluble grit but I hate to go by "probably". In the UK insoluble grit is granite or rock used to grind food in the gizzard while soluble grit is a calcium source like oyster shell or limestone, two very different kinds of grit. I saw Grit on Kalmbach's Layer feed but not their chick Starter. I don't know what kind of "grit" they mean. Maybe someone could contact them and ask?
When I e-mailed Purina a few years back and asked them about grit, they did not add grit to any of their feed. The only one I've seen that does is Kalmbach (there could be others) but I would not assume any do unless it is listed. And clearly listed and explained at that.
