Heat index does not mean that much with chickens. The real temperature is what matters because of the way chickens cool themselves. We sweat and evaporation cools us off which makes us feel hotter in humid heat since evaporation is slower in high humidity.I have a serious question re the Astrolorp breed and the Georgia heat. It can get very hot and humid in southern GA sometimes reaching index heat of 103 with 70% humidity in the summer. How do they fare in this type of heat. Thank you for replying.
Australorps will be fine Georgia as long as they have shade and water to drink.
