This is early on before I had the chickens. I haven't added the roof or plastic on the walls so this is pretty much it. The pop door is on the right in that picture. The run is secure so we don't close the pop door at night. We do get eastern canyon winds, but they will stop during the winter. The run is a 7'x7' cube and about a 3.5' x 3.5' coop. They have one nesting box that is inside of their coop. The roof of the run will slant toward the front because that faces south. Our prevailing winds are East and West (so the roof is not a sail). We get snow. Some years a lot, other years none. Sometimes it warms up and melts off quickly, other times we don't make it to freezing for weeks on end after a storm. Much of the November-March season it does get above freezing each day (or close to it, especially in the sun). The coop/run will have good south sun in the winter because the trees to the south of it are not deciduous. We plan on running an extension cord out to the coop/run to heat water during periods of freezing temperatures . . . also to run lights. We just don't have the $1500 to run electrical to the coop. The top of the coop has hardware cloth and then a 2"-3" gap before the corrugated roof for ventilation. I plan on placing an LED rope light above the hardware cloth to light the coop during the winter months. Next spring, I will add on to the run - another 8'x8' cube or so. . . so I can add a chick or two (depending on how much time I think the chicks spend in the coop in the winter). The coop isn't that big, but with the run I think they might be OK to have a couple more in there with the outdoor space enlarged. I will not cover the additional run space because I plan on planting it with things like alfalfa periodically. I can always add an additional shelter for the chickens in the new run - like a dog house with a roost in it. We put pine shavings and shredded straw in the coop and pine shavings and whatever organic material from the yard in the run. So far, no flies, no smell, and the chickies love it. I have a brite tap waterer and LOVE it after using regular fountains for awhile. The water stays pretty cool, clean and I only replace it once a week (three hens). We got our first egg today!!!!
