I was at a field trial for hunting dogs using quail. When I was talking about the Coturnix Quail we got on the topic of size. I was told that they use only the small ones so I figured that's what I have. I was told the mediums and jumbos don't fly when they use them for training. And when I mention where I got my Breeding stock I was told I have mediums and they do not fly and you need to kick them out of the way in the pen. Sounds like mine. So is there a small and medium Coturnix? We are aware of the Jumbo's.
