I am new to the whole chicken thing and am in the process of designing our coop. I keep reading about in cold climates you need to have an insulated coop so the chickens keep laying all winter. Is this insulation like insulating a house with fiberglass batts in the walls and ceiling and if so do you need to cover them with plywood or drywall etc.. in order to keep the chickens from pecking at the insulation. I know it is a strange question but all the coops I have seen around here have just plywood walls but I dont really feel like spending a million dollars on heating a chicken coop for 5chickens. It gets pretty cold around here (Cedaredge, Colorado)--this am is 17 degrees. Any help would be much appreciated. Thanks.
