I don't know where the information is that I was reading but I always wanted to raise quail with banty chickens loose on the farm. They adopt them as their own and teach them foraging and etc. That always seemed like a good project.
Unrelated but there was a guy here, in Ohio even I think, that had a big post about raising them and showed his boxes. They were narrow like two feet wide and long like ten feet long with a screened top with natural scratch and debris in them. Lined up like garden beds in his barn I think. Thats how I see it in my head I guess but I'm not sure. Seems like Keith C knew the guy but I'm not sure about that either. There was lots of info in that post about successfully raising quail.
That is me. The boxes and quail in the pictures are mine. In a good year I raise and sell tens of thousands of coturnix quail and thousands of button quail. I've raised them since 1995. I've raised and sold lots of bobwhite, in many colors, Gambels, valley and blue scale quail too, but don't have any right now.
For anyone interested in learning more about raising quail and homesteading, Quailcon, the International Conference on quail and homesteading is on Labor Day Weekend in Miamisburg, Ohio. It"s a 3 dag event with camping available on site. We get a few hundred people from all over the US and other countries. The main focus is on coturnix quail, but there's a large numbers of classes and presentations including hands on butchering, cooking, other livestock,, selling plants, medicinal herbs, first aid, marketing and more. I"m a paid expert at it every year. Last year I taught and spoke for around 14 hours.
