TSC wont carry purina game bird starter.... Never have. For some reason they wont even order it. I actually get mine at a local mom and pop lumber yard! As Martha said, turkey starter will work in a pinch, but if your gonna raise quail, you need the proper feed! I just use play sand or even dry...
Your feed flying every where is due to the wrong feeder. What your birds are doing is "dust bathing" in your feeder! I use these....

These are great for small numbers of birds too...
