Mary, it can get even more confusing. Don’t we always come up with ways to muck things up? In the UK and probably other places, there are two different types of grit. One is called insoluble grit. That’s the stuff they use in the gizzard to grind up their food. But oyster shell and other calcium supplements are called soluble grit. That’s the stuff that the acidic digestive juices dissolve so they can use the calcium in it.
So for a lot of our forum members just saying grit isn’t enough. They might not know which grit we are talking about.
