Hi! I know there are several posts on this - but I really couldn't figure out how to join that conversation. I am very new to posting. Sorry. We live in Michigan and have 15 Rhode Island Reds. We have a wood coop that is off the ground with an attached run. The coop has a window - but no other ventilation holes. I want to know if the chickens will still come outside and eat (their food is hanging in the run) or if I have to move their food inside the coop? Also - same for their water. I plan to buy a water heater for our metal waterer to keep it from freezing. How do I make sure my birds don't die this winter from the cold? I have read NOT to put in a heat light because the person said if the power goes out you could lose your whole flock in a night. Our power went out many times last winter - so this makes me nervous. I am even MORE nervous though about the birds dying from the cold. Any help you could give me would be much appreciated. Thank you so much!
