Water: YES! GET some water in that coop stat!
As you can see in my build thread (Linky thing under my avatar) and in it the water is 100% 365 available in there.
It’s all about correct thermal ventilation. It may be hot but, in there is real thermal variation with a breeze than they will adjust and be either close to or fine. Start making “Tupperware frozen water containers in the freezer to be added to their water era ASAP.

Thanks for this! Awesome coop, by the way.
During the day, the coop and run are in the deep shade after about 8 AM. The fan is technically an exhaust fan, but I installed it with the intake outside under the covered run, so it stays about 10 degrees cooler than even the coolest shade. The coop has constant airflow and has remained below 95 when temps over here hit 110 with the heat index. So I feel like I'm doing something right there. Probably because I grew up in the mid-west, and even after 20 years here, I STILL don't tolerate the heat well, so that's all I could think about when building the coop, HA!
I also placed some frozen gallon jugs of distilled water in the corners of the run and ice in their waterers. They licked off the condensation from the jugs, but they were comfortable all day, and no one was panting or showing signs of discomfort.
Of course, coop temps and humidity rose when all the ladies piled in there and that's when the panting started. It might not have been so bad if they weren't fighting over the same roosting bar and piled on top of one another. It did stay below 90, though, and steadily dropped overnight.
I'll add a waterer to the coop today so they can have access to water overnight.
Pictures are forthcoming. The last storm downed a tree and punctured the roof so that's been a priority.
