I love that idea! I've been approached about supplying quail eggs and possibly meat regionally so in just in the learning/research stage. A thread on commercial production would be really helpful.
I'm especially interested in finding out whether anyone has had experience raising/producing quail on a well-ventilated greenhouse environment. If I have to build a shelter anyway, a simple PVC greenhouse with an area for feeding/water and occasional confinement (to make them easier to net for harvest) would be something I could do. And heck, of the quail didn't turn a profit, I could reuse the greenhouse for some type of winter crop.
