In in Arizona and we have misters running through the top of our run. Our chickens LOVE them and spend most of the day under them. You can buy a single one at Lowe’s for pretty cheap. They lower the temp in the whole run and they also keep the ground cooler for their feet. Mine are still teens though and not really “street smart” yet because they still spend a lot of time huddled together despite the heat. I hear they smarten up as they age! Maybe ours will figure out the wading pool at some point.
