At 8 weeks, I'm not seeing much difference between the original quail and the Jumbos. The Jumbos look larger, but that may be a self fulfilling prophecy. Or the originals were jumbo sized. I don't have a point of reference. What should I be looking for? I know, 12 oz live weight versus 16 oz live weight ain't much. Maybe I was expecting more with an inviting name like jumbo quail? Like jumbo shrimp? Or a miniature elephant? ("I am not a shrimp, I am a King Prawn!"

)
The 6 month olds have fat on them. Feeding Purina Game Bird 30% protein.
The 11 week old Jumbos were on the smaller end and about the same size as the originals. Made the 1.5 lb cockerels look larger than they were. (The chickens didn't crow this morning.

The aggressive male quail was yelling his fool head off. He's in solitary since the other males didn't like getting mated.

If I don't see mating from the selected male for the breeder pen, he may get called back. We wait a week.)
Final surviving count to butcher for the jumbos: 11 female and 9 male. I'll have to check my records for the lost ones.
Tried to separate the largest females with the largest male. Touchy feely. Now to wait for eggs. 3 roosters left to butcher. And 3 cockerels.
