Yep, I also have a fan that blows into the coop for warm summer nights and got summer days.We definitely don't get the heat you Southerners get. Shade and fresh water, fans, electrolytes and frozen treats during the heat waves is our main go-to's.
One of our biggest issues is the nest (hot) boxes especially with the loungers/broodys. Fans set on low and I've done frozen water bottles buried in the bedding on one side seems to help, also. My nest boxes are good size at 14 x 14 so they can adjust themselves to the chill bottles.
