+1!living in the very dry desert I have tried A LOT to keep my chickens cool. I have found that fans are the best even with a very little moisture in the air the circulation of the air keeps them more happy. Lots of water to drink and move the air. blowing it at them. IN Arizona the mister with a fan is the nicest for the chickens. the size of the fan depends on how may girls you are trying to keep cool..
they will huddle up to a small fan.. they need room to get some air in their feathers. Windows are nice because you can secure the fan to keep it out of reach of wings and beaks or poop deposits.
My fans are just on the other side of the chicken wire. Some people don't have electricity to the coop but in the hot months we run weather tough extension cords out to the coop to keep the fan running. cover the connections with plastic bags to avoid moisture at the junctions (rains etc).. we also provide frozen treats; wading water and always fresh clean water to drink. Think about what keeps you cool when you are too warm.. Air baby.. lots of air
We buy the 20" wallyworld box fans, usually $15-$16. Turn them on when the temps hit 95, turn them off in October. Have never lost a bird to heat!
