I live in south Louisiana and it rsrely gets below 30 here all year, but tonight it will be 25 and 16 tomorrow night. I am very concerned because of the wind. My coop is open with roosts inthe open area, and the nesting area isout of the wind. My chickens sleep on the roosts which are in the roof, but the 20-30 mph winds out there right now are howling underneath them. I'm very worried.
