Cuttlebone will work. It's good for their beaks and for calcium. My adult quail never did touch it, but it's worth a try.
Also, add oyster shell grit, it's important. It's to help them digest their food as they don't have teeth, it also provides calcium. And it's inexpensive; Around $3 for a 1kg or 2kg in your local groceries store.
