Comparing quail sizes

I've decided to keep a bit of a log of my quail sizes to not only help choose my breeding stock but to also possibly help other decide where to purchase their next stock from. I originally got my first brown coturnix quail from a random person on eBay advertising jumbo quail. I have had this stock for over a year now but have become frustrated that even with choosing the biggest eggs and feeding Gamebird feed with 30% protein my birds are only 6.5- 7ounces at six to seven weeks old.

I now have hatched 40 chicks from JamesMarie farm, 45 chicks from another source in California claiming to have jumbos, and a dozen chicks from my own stock for direct comparison under the same conditions. I hope to make weekly weigh ins on the chicks and choose the best for my new breeders. The JMF chicks are now three weeks old and have had the first two weigh ins and the other two sets have just been born the last two days.

I was happy with the first results:

JMF 2wk hens range (69-110 grams) average: 84.55gram
JMF 2 wk Roos range (69-91 grams average: 83.11gram

JMF 3 wk hens range (116-172) average: 138.71gram
JMF 3 wk roo range (117-148) average: 137.82

This makes them on average close to 5 ounces at three weeks. Hopefully this comparison once complete will help me make some good choices in my breeders and maybe help some others out there too.
