We have four four-week old chirpies in the process of transitioning out to a catawba coop--daytime only this week, full time starting next week, no more heat light anytime. They are standard, supposedly cold-hardy breeds (2 EEs, 1 Dominique, 1 Cuckoo Maran), mostly feathered, and seem to do great with no extra heat during the day, when it's been in the 60s. It does get really cold here in the winter and now I'm starting to wonder if this coop will be adequate. Since we went through the trouble of building it ourselves and don't have tons of space to begin with, I'd really like to make it work!
Has anyone gone through a full winter in a cold climate with an ark? Do you keep the ramp down on cold days? Have you used a tarp and/or shower curtain and has it kept everyone safe and happy?
Thanks very much for any advice.
