Where I live the coldest it usually gets is in the mid-40's, so I'm not too terribly concerned about winters. But in the summer (that lasts from May to October), it get's into the mid-100's with a lot of humidity for weeks at a time. I haven't built a coop yet, but what should I look for in my design to make sure the poor things don't overheat? Obviously windows and one of those rooftop whirly-gig vents, but I still think it would still be too hot in there for them, even if they were outside in a shady run. Inside my dogs bogart the fans, but I just don't know how I'd keep the chickens cool enough out there.
