Do you use game bird not medicated starter. We (or at least no one I know) can get not medicated up here (Qld) anymore. I have found a game starter for quail that is not medicated.
I use a non medicated organic crumble for the first 3-4 weeks , gradually introducing them to the laucke game bird finisher mixed with a free range grain 50/50.
