We hit 109.8 yesterday and 107.6 today. Luckily so far all is fine. I keep a water mister in their run and ice cold water as much as I can. They stay in the barn and only go outside late in the evening now. They just lay in the cool dirt of the barn and pant. We have a high barn roof so that helps some. I've hosed the roof down a few times daily too. Hope every ones chickens make it through this. Prayers go out to you all.
