Hi likes2grill! You got your quail from us, so I'll respond with what I know. We got our original quail eggs in a 50/50 mix Jumbo Brown/A &M's from a reputable breeder in GA. The offspring of both have been larger than the pharaoh quail we used to raise 25 years ago, but neither are 1lber's. Although we don't have a scale, I'm guessing 12oz. for the largest A&M's and 14oz. for the largest Jumbo's. Our pharaoh's were more like 10oz. by comparison. We found the A&M's to be slighty, but not too much smaller than the JB's, and they both taste the same. We decided to keep mostly Jumbo's for breeding as they are a bit tamer than the A&M's and easier to sex. We have one pen that has 1 male and 2 female A&M's with 1 male and 2 female Red Tibetan's (but have yet to get a Tux from a hatch). The A&M's I kept for breeders were the largest of the bunch that showed the least black. Most of the A&M's we've hatched have been pure white, or white with a small dot on their heads. As with the JB's, our breeding program is focused on bird size and egg production. DH wants to get rid of the A&M's and focus on the Jumbo's as we are getting some huge eggs from the Jumbo's and they are calmer birds. He's in charge of the quail and I do the chickens so it's his call.
I know you've met him and my son, and hope to meet you someday as well. I'm usually on the chicken side of the property as we have quail buyers come to the quail side for biosecurity, as many quail buyers are also chicken owners. Please feel free to email me with any questions, and have fun with your quail!
