I started raising quail again last fall, I raised some many years ago that were some little bitty things. When I got birds again I got some eggs locally form 2 different breeders well at about 6 weeks most of these birds weighed 6-8 ounces with most of them being alot closer to 6 ounces so I kept the biggest and bred them I am now getting eggs from the second generation and have some in the incubator. Well a while back I bought some eggs fro eBay out of Arkansas with the lady claiming 13-17 ounce quail and I figured it wouldn't happen but oh well. They haven't actually reached that but I am really impressed with the results. When I weighed the eBay birds today they are a littlle under 8 weeks old, I have about 10 birds weighing in 12- 12.5 ounces. Not moby quail but way bigger than the original birds I aquired. They size wasn't very consistent though some were alot smaller more like 9 ounces.
