For those of you living in cold country, If that's a silly question, just laugh at me. This is my first cold season with backyard chicks. Only have 3 and they have become our pets. They have an A Frame tractor set up. Upstairs lots of pine shavings. Have also covered the top with a plastic tarp to keep any major draft from entering any areas DH didn't caulk. temps got to about 25 last night. Supposed to get colder tonight. Thanks
