The mineral grit is like the Mineral Grit Bucket that I get from VitaKing. Yes, they would have loved that. Mine do. I just put that out now and then as kind of a treat for them. They will gobble it up. They are spoiled. That has lots more in it than just grit and that's why they like it so much. But just regular grit is what they need for grinding their seed. They may also miss the anise in it. They don't gobble regular grit like they do the mineral grit. They will just take it when they need it. I wouldn't worry about it. They will take it when needed. You can always order the mineral grit from Vita King and just mix a little in now and then. You can buy it in 11 or 22 lbs. Used to come in buckets, but now get it in bags and the shipping is much more reasonable. I couldn't get it for a long time, as the shipping used to be as much as the grit or more.
