We are going to get chickens for egg laying. We live outside Orlando and get really hot (upper 90s) 3-4 months of the year and can get hard freezes in the winter (usually only a few hours at predawn for 1-2 nights at a time). We also have loads of rain and humidity. Any special considerations for a coop/run? I see lots of info about winterizing, but nothing about controlling heat. Any advice or suggestions/resources are greatly appreciated.
