I'm planning on starting my flock this summer, and I'm wondering what the maximum temp. for them is. While our house and garage are relatively cool, the climate in my area can reach 100 degrees in july and August. We are planning to move them outside in late august or early september because it is so warm. Oh I'm getting BO, Barred Rock, Polish, EE, NH Red, and Australorp hens, if that is helpful.
