Thanks for the kind words, everyone.. He is doing well today and eating/drinking.. I'll keep a good eye on it and record weights as it grows.(I am avoiding "he" as I am hoping it's a hen..lol)
Just to note, in case you get another "big" egg,. I candled the 21 gr. egg and only ever saw one yolk that's why I decided to hatch it.. Check them if you get another, we could be onto something. I know little of genetics outside of what Moby has posted here(thanks, Moby), so it could just be a chance for an even larger quail breed. This egg only took a few hours longer to hatch but was still @ 17 1/2 days...
