Hello! I built a small chicken coop, based on the "Kippen House" plans. After living with it for 3 years, I find myself continually second guessing the design, and if I should do more to add to what I have, especially given winter nearing (I live in Colorado). So, I thought I'd reach out and get some opinions from you all- the experts! Specifically, I worry that the exterior is cedar boards nailed on. Should I put plywood behind them, so that it's a solid surface, without the small gaps in between the boards? The past few winters I wrap foam insulation in thick plastic to cover the wire openings, and we cover the whole thing in a blue tarp overnight if it's snowing or especially cold. I just don't think that's the best system, and want to make sure that I'm doing everything I can to make sure my girls are warm, safe, and dry throughout the winter months... The chickens free range during the day, so they do not live in this 24/7, but more so to eat, sleep, and lay. Does anyone have any ideas for me of how I could improve upon what I have? Or, should I look at getting a new coop that would let me rest easier? Note, I have *very* limited carpentry skills, and was super proud of myself for building this in the first place, so any retrofitting will need to be done at my novice level. THANK YOU so much for any ideas you might be able to provide!!! *these photos are from right when I completed it, before I added straw to cover the floor. There's now tons of straw & the girls are much bigger!
