Pheasant is over rated. I think the limit is only like 3 per day in the US.
Quail hunts... get out your $$$. That is where the big boys play.
If you are doing pen raised birds... Chukor are the way to go. They jump up like a quail but are larger like a pheasant. When I had more time one of my buddies and I would partner up and buy a couple hundred small birds of each for like $1 a piece. We would put them in some old wooden horse stalls. They mature in like 90 days. If you give them room to fly they will develop better and fly better for you. We would work his dogs in the off season with them. Its was like that movie birds. We would bail in there with dip nets and start netting them to take to the pasture and work dogs. Some times we just netted a few and threw them straight on the bbq pit.
Nothing is like wild birds but its pretty fun for the dollars spent IMO.
