I have a new 6 x 6 gabled-roof, Amish-built coop. I have been wondering about the need to insulate it or not. I plan on covering the 2 windows with plastic, to create the dead-air zone, etc. and I had them cut a ridge vent in the ridge, and put in 3" x 6" vents, up high in each gable-end wall. I don't have my chickens yet, but will be getting some of the more "winter hardy" breeds as day-old chicks in Spring '09. I was asking someone I know if "they" insulate and/or heat "their" coop at all .........we both live in northwest NJ..............and his answer was "absolutely not"! He said what "he" does is tack carpeting to the roosting boards, so the hens can hunker-down onto their feet, fluff-up their feathers, and not have to stand on cold board roosts all night. That sounded like a great idea to me!! (I asked also, "what if the girls poop on the carpeting"?..........he said, just rip it up and add some new!) What do you all think? There will be nothing between the chickens and the cold outside air but the painted T-111 plywood outside of the coop...................... Thanks for any thoughts!
