I live in AZ, and it climbs up to even about 120 in the summer, so my chickens definitely get hot! AZ is moving into "monsoon season" but it's still super hot, so with the crazy storms coming in and the heat, it's definitely bad; very humid, and very hot! We put them in a pen in our old garden, letting them out to free range only in the morning and when it cools down at around 6-7, and during the day they stay in the pen. At night, they go into the pen/coop. I keep it completely ventilated, nothing blocking anything if we can help it. Another thing I do is freezing at least 1 water bottle per chicken each night and placing it in the pen during the day where it's shady or where they most frequent (for mine, it's under an eggplant plant), along with a jug or 2 that I fill up with water when all the milk is gone and that takes a little longer to freeze so I do it ahead of time. For their water, they have one of the ones you can get from
Tractor Supply. It's just basic plastic that's white-ish with a red water tray/where they drink from. I freeze an extra water bottle for it each night and put it in their waterer when I refill it each day, leaving the cap off so as the ice melts, the cool water goes into the waterer. Another thing is that I go out every hour to hour and a half and, using the hose, very gently mist down the entire pen so it's cooler for them and wets the ground. It does make it a bit more humid, but with frequent mistings, the humidity seems to be overrun by the coolness. lol Just make sure to keep a close eye on them, and have a temp pen set up somewhere cool in case one of them seems to be getting heat stroke or heat exhaustion. You can also try giving them some frozen treats like grapes, corn (which I heard was bad due to it being harder to digest so they produce more heat trying to digest it, but I'm not sure on that), watermelon, etc. Good luck to you and your chickens!
