I have 12 chickens growing between chicks and chickens. Sunday was a warm day here in AZ, as summers usually are, and I wanted to do something to help cool them off. I didn't want to spray them with water because birds don't usually appreciate that. I'd been sitting in the coop with them for about half an hour, long enough for them to scratch my shins trying to run up and slide down my legs. Several had set on my legs for a while, and it was a pretty tranquil moment. I got up, thanking the chickens for their company, turned on the hose and hosed off the corner of their run with water. When I turned it off the birds ran over (did not hesitate) and plopped on their sides. I stood mesmerized as they dug little holes, rolled in it, ruffled their feathers, rolled more... The ones running in behind the first would gladly take facefuls of wet sand. Several of my fatty americaunas sprayed sand over several other chickens.... nobody cared. They closed their eyes and just rolled and rolled, dug and rolled, dug and rolled. It was very theraputic to watch them relax so thoroughly. I'll have to do that again sometime. It's so fun to watch.
