I am very new to this chicken raising and live in ND, -40's during the winter. I have 2 plymouth rocks and 3 easter eggers. We are starting to plan out our coop which will be in the garage. I have tons of cardboard and those packing foam thingys that I am thinking of using as insulation. Would this work or not? Any pointers or advice is greatly welcomed. I have learned so much just by reading this wonderful forum. Thanks so much!
