They're cute? Run in sequenced order? I don't know, unless it is to sell to better restaurants. I know a guy who raises them, lets them loose on the back wooded parts of his farm then rents the farm to hunters for good money.
I'm raising the jumbo coturnix quail because I tried meat chickens this past spring and won't do it again. I don't have the time to process all those birds myself nor do I have the room here to keep them. I've heard the jumbo coturnix are all dark meat and since they are small, they are easy to keep and process. Also prolific egg layers.
I also raise button quail, as do many others, but that's just because they are cute and fun. Can't eat 'em. Well, you probably could but it's alot of work for one bite!
So now I have chickens for eggs and quail for meat which is why I'm raising them!
