When I turned mine on earlier this hot season, they were standing wings out. Very quickly they were standing normal and very happy!I finished installing the misting system in the coops today. The chickens all seem pleased. When I got done, and turned it on, there were happy clucks from all of them. Even with our high humidity it does help. Between the fans, and the misters, the coop was very tolerable, even though it was 97 degrees out today.
