Hello all! We are raising our first batch of chickens and are heading into cool Autumn weather in Chicago. Hubby and I are planning our winterization of the coop/run. The big problem.... the coop/ run will be shaded by evergreen trees all winter! How can we keep the girls from freezing without running heat all the way out to the coop. Do you think using thick clear shower liners as draft stops will help create a little more heat? Thank you for all your advise. Six months into having backyard chickens and I'm still loving every minute!:cd
