First let me say that this is an awesome site! SO much information..... I am interested in having ~4 egg producing chickens in my backyard. I live in Aurora Colorado in a unique little area that allows me to have small livestock (a neighbor has chickens and bees). Anyways, I want to have fresh eggs and possibly even fresh chicken once in a while. The location I am considering is approx. 6'x10' and I want to build a permanent coop. The area I have selected is on the sunny side of my house (East side). This would include the coop and run (as you can see it's pretty much a clean slate ready for whatever). There are predators around so "backyard free range" probably isn't a good idea though my neighbor does it (but has also stated she's lost several too to predators). I was reading and the 4 sq/ft recommendation is no problem as I have about 60 sq/ft area chosen and only want 4 or 5 chickens. My main concerns is I live in Colorado, how do I keep them safe and comfortable in the winter? It seems a decently non-drafty yet ventilated coop is best (was thinking of designing openings at the roof level) and since this is Colorado, humidity is not too big a concern. Providing power (for a heat lamp) is not easily feasible. I haven't had the chance to pick my neighbors brain yet either but I plan to. I also read about the "winter break" for chickens and that isn't a problem. I'm building a personal convenience, not a production facility. How "stout" should I build this coop? Meaning, insulation, running water, electricity, something a Tiny House fan would move into?
