I raised Bobwhites, Chuckar and Ringnecks when I was doing a lot of dog training. Here in Indiana, you have to get a game bird breeders license, and they are pretty picky about releasing pen raised birds. They want you to keep release records - date, number of birds, etc.
I bought fertile quail eggs and hatched them. Those suckers are TINY! The day olds could squeeze thru 1/2" chicken wire mesh that I had on the brooder. I had to put blinders on the ringnecks to keep the pecking down to a minimum when they were adults.
