One of my prize birds died of a heat stroke two years ago. Living in South Carolina, keeping the hens cool is quite a task, but keeping a cover over the pen for shade and hooking up an electric fan has been very helpful. Also, I place ice in their water which they seem to enjoy, but I discovered something new today which I want to share. My most intelligent bird was standing in the bowl of iced water and looked very comfortable. Apparently, this produced a cooling effect for her. I filled a large baking pan with ice and water, so all three of my beloved birds now have cold feet on demand.
