Evaporative cooler in the coop - question?!

[centrarchid]

Well, the evaporative cooler isn't going to work for us. It doesn't help. -have three sides of the coop open with big box fans circulating the air. (The coop is under a large oak tree for shade) The drinking water supply stays very cold and the mister and two fans near the run is working well. The run is dry and they are dust bathing as usual. The grass in front of the run is getting the residual water. The fine mist is blowing through the run, and it is nice. -looking forward to fall already....

I use such successfully here with fish. System does not work well then following realized: ambient humidity high, air flow too low, or air flow too high.

-definitely think that the humidity is a significant reason that the cooler doesn't work well here.

If I had the money to throw at it and desired a passive system for reducing heat stress, then a large stone would be placed in shade and wetted each night. Stone would cool during night and be slow to warm during following day. Birds could stand on it to keep feet cool and thus body temperature down. Better yet would be a cave made of stone that is big enough for flock to get out of sun and also get a little breeze.
