here are a couple of pictures of my cooling setup. it worked last summer when the temps were in the 110's, so this summer has been easy so far.
This is the people's eye view. The corner isn't a 90 degree angle. I draped the shade cloth over the bird netting and fastened it to the fencing with zip ties. this is the wide shade cloth, and there are two rows of it. You can see the cobra mister toward the front edge of the shade. The mist also drifts with the breeze so it cools other areas, too.

THis is the chicken's eye view. You can see the hose mister (tiny hose with little nozzles about every foot or so) draped across the opening at the top. This mister mostly dampens the shade cloth, but it, too, allows for drift. It has the added benefit of keeping the ground a little damp and the grass stays green. That is a volunteer sunflower inside the run in the foreground.

The tree works to help for part of the day, but there just wasn't enough shade IN the run when I set this up 3 years ago. I take off the front panel of shade cloth the end of September so that they will benefit from sunshine during the winter.

misters and shade
edited to add:
I just realized how abrupt that sounded. I used shade cloth over a corner of the run and I have a mister set up so that it sprays some of the water on the shade cloth. It acts like one of the old swamp coolers and the whole corner of the pen is 10 degrees cooler' I'll post a picture when it gets light out.
