It is 102 in the shade here in the afternoon. I have iced foot baths, lots of shade, an oscillating fan, cool treats, I water down the ground, but I haven’t tried a mister. I had a mister that I bought for humans, but the humans were not that impressed (the youngest human likes to be soaked, not misted), so out to the chickens it goes! Not entirely sure what the chickens think of it either, but at least they didn’t freak out when I set it up (no broken wings). Picking a spot was problematic. I didn’t want it to spray on them, or the food, or into the coop. I settled on the corner of the run where wind blows the mist either way.
