We usually let the girls forage around the compost area. Right now it is way too hot even at the bottom of a chicken a hole. I set up a Mister system. They're likeing it.
Yes, it's horrible, isn't it? I am in the bay area, not quite as hot, but my flock is pretty miserable and hanging close to the mister. Wish the darn thing didn't leak where it joins the hose...
