I live in the heart of Florida, my coop has an aluminum roof and no shade. I think you already see my dilema. It can reach well over 100*F in the sun here on a normal day, and today we are under a heat advisory predicting temps of about 112 and higher. Im so worried my chickens (silkies esp) are going to start having heat strokes. I have a fan set up in the coop, but it literally feels like heater...just blowing hot hair. It is just as hot out side as it is in the coop, so moving them is not going to help. I go out during the hottest point of the day between 1-2pm, and hose down the roof of the coop and spray down all the chickens. This works great for a while, then it becomes like a sauna. There is no air movement out here, at all. Just baking heat. I dont know what else to do for them. They are taking it relatively well, but I wish I could provide some relief. Does anyone have an idea of a cooling system I could build for them? If I could afford it I would set up an window ac unit for them. Thanks for any tips you can give us!
