Doesn't the starter food have grit in it? I know I either read somewhere that it does or they told me it does, but I can't find it on the feed bag. What would it be called if not "grit"?
I gave them some grit when I gave my 2 week olds some mealworms, but they were eating so much grit that I would be worried to leave it in all the time for fear they would eat too much and fill up on it like I read on a different post.
