This very popular video shows how to build a fully enclosed run especially designed for quail (but can also be applied to chickens and other poultry).
Predator proof and rat proof this run design is easy to build because I made it and I'm definitely no builder! Basically, it's a framework with avery netting/mesh wrapped and tacked from the inside and dug-in to ensure nothing can dig under. Standing the test of time, I've personally been wrapped at how well the run has worked and I've also been happy and humbled by the online community support sharing and liking the video.
