Pertinax -- not much bigger than CPQ if at all, some suggestion they may produce an excess of males -- 90 pounds a pair is probably a bit much to pay, but not way over the top, given that some pet shops will charge you 25 quid for a baby Budgie.
Looked about the same size as CPQ to me - so used to other quail being bigger that it caught us off-guard. The bird kept appearing for a brief trot around then returning to this little hidey-hole as soon as he noticed humans!
