Total newbie, here. I'm getting ready to assemble my pre-fab chicken coop, and I'm wondering about interior needs such as insulation and paint. I live in the mountains of Colorado (8520 ft) and it obviously gets a bit windy and chilly up here. ? #1: I've read that my chickens (Ameracaunnas) won't need any insulation or heat source, but I'm still worried about them freezing on super-cold nights. So I am considering reflective foil insulation. Has anyone in the Rocky Mt region used this type of insulation w success? Keeping in mind I've purchased my coop prefab and I'm sure it's not top-of-the-line. ?#2: My coop has a pull-out vinyl tray for cleaning and the interior is wood. I'm considering painting the interior white for easy clean up (and maybe some xtra warmth as the paint might seal those drafty cracks- it does have proper ventilation w a hardware cloth covered window). Advice?
