I know this is a old post but I hope this will help.
go to
ebay and search quailkingjosh, or Texas A&M jumbo quail eggs you will find them.
we are new to the quail raising, our first hatch was 2-22-2017 and had real nice jumbo browns, and decided to try the Texas A&M just for a try, the eggs we got from them were all 14 to 16 grams each. The hatch rate was only about 55%. I'm sure you all know how that goes.
Anyway they are 4 weeks old today, 38 birds smallest one 178 grams the largest 5 are 235 to 249 grams.
Nice size but question is a few of the birds have the black spot on their head but also some brown feathers, does this mean they are crossed with jumbo brown?
Thanks for any info
