Are these Standard or Jumbo??

[P-heasant]

So I am going to purchase some jumbo Japanese quail, this is a video which the man posted. They look either standard or just a bit too small to be jumbo.

I have screen shot pictures from the video

I am no professional but these in the video are his breeders and look smaller compared to other jumbos Iv seen.

What do we think?

I can’t tell anything from the pics. Besides not knowing their age and never having seen that hand before for scale…
Visually, my own birds can seem to doub their own size just by standing or fluffing feathers differently. Don’t know what to tell ya.

Well from images Iv seen, I thought they may be equal to size of a wood pigeons but these breeders only seem to be around a handful.

Other than size are there any other characteristics to look for?

What should a jumbo weigh around 3 weeks old ? Any ideas

The current standard being 10 oz at 6 weeks to 14 oz at 7 weeks. This standard was reset by the Texas A&M Whites for use of commercial purposes. You can look it up by searching Diamond Ranch.

Adult weight for breeders and is not of concern for earning the name of Jumbos or Giants. However, they need to be BIG to produce Jumbos or Giants.

So if they should be pushing 10- 12 oz at 6 weeks. ... (there was no discussion for 4 weeks.)

... harvest at around 7-9 weeks of age. Some varieties like the Texas A&M and Jumbo are better suited for meat production as they’re a larger-bodied bird, obtaining a final weight of 13-15 oz.

Purely Poultry, which sells Brown Jumbo Coturnix advertises that the birds can reach UP TO 14 oz. at maturity.

Realistically, the birds, like all living things, vary individually. You choose the largest, best built and healthiest to breed to improve size, conformation and vigor.

If you have concerns why not buy from a well established breeder with a good reputation like Southwest Gamebirds or Myshire? Especially if you are planning to use the birds in a breeding program, you want good genetics. Don't cripple your plans by starting with iffy birds.

Apologies I am in the UK. We do not have well established game breeders for quail in my area.
