After reading for the first time about open air coops on a thread here, I'm totally wondering if that's the way to go or not. Woods' book was written in the early '20s - a lot of our thinking has changed since then. He also mentioned sleeping on screened porches in the winter and I don't see how that has the health benefits he's touting. I sure wouldn't want to do it, nor do I want to sleep with my windows open in the winter, regardless of the health constraints of "poor air". So I'm wondering - are open air coops, in the frigid northeast (or wherever) - a good idea, or not? Any thoughts would be appreciated, as I'm thinking about a new coop and don't want to have to do this again for a really long time.
