Crowing
Normal coturnix can run a whole lot smaller than 9 ounces. Last year I bought a dozen week olds from a local breeder that only hit 6-8 ounces. Not doing that again.
Here, we divide them into 3 lines. Light, medium and heavy line. But they are floating.
Originally the light line, most related to the origin of the Coturnix Coturnix, had around 120g. They were used for egg production, as they layed very much (16h cycle) and ate only few.
Rarly found nowadays. My lightest are around 180-200g.
Most common is the medium line which has around 250 to 300g.
The heavy line, most used in meat production, is 400 to 450g. Some individuals can reach 500g.
As wrote before, the edges are flowting. Much is mixed.
I have a girl, out of a medium line order, which has 380g.
