Nice article, quail definitely need a natural environment to stimulate broodiness. No guarantee they will however providing an aviary style pen, hidy places with foliage, hay to make nests, your chances of getting a broody quail improves. Nice job!
Very helpful detail, and the photos, especially of the brood patch and the nesting female wee very helpful. I would recommend some editing to improve the grammar issues, but otherwise, this is a very useful article.
