We're in the process of designing/building a coop that will be located in upstate NY (Capital Region Area). In the winter it can get quite cold (sub-zero on the coldest nights in the winter). Do coops require insulation in climates such as this? Does a heater inside on a thermostat suffice? Both? I'd really appreciate some general thoughts design tips/advice from some people who have gone through the winter before regarding what they've learned in the past. Thanks in advance!
