My coop is insulated and it was still 80 inside. I have a shaded area outside for them by in the 90 degree heat they were panting with their wings lifted from their sides. There was a nice breaze going by you could tell they were to hot. My dd gave them ice yestardy. They seemed to enjoy it . I kept taking out cool water every couple of hour to them. I worry during the week because I work a 8-4 job and will not be able to take water to them every couple of hours. This is only April and I am worrying about the next few months getting to hot for them. How do you keep your flock cool in the heat?
