Thanks everyone for sharing about the timer. I will have to look for that one next HD trip; I have already picked up drip line and mister nozzles; mine will be at the top of the building on the outside, to help cool the air going into the chicken house (which is 12x24, open along the 24' side) Already have shade cloth on that side. In the past our usual high for the summer is a few days of 105-110 but last year we had a day of 115.
Since we are cooler than the valley I"m thinking I could set the timer to come on about 2:00 for say 15 min, then off for 30 min then back on for 15, ect. With four cycles it would run from 2 until 430. If I work a day shift I'm usually home by 5 and let them out to range until dark anyway. I could also monitor temps and run it manually for another round or two if necessary. But we are lucky up here; it starts cooling off most of the time as soon as the sun is going down and night temps are comfy except a few nights where it may stay in the high 80s.
also when you are looking at mister nozzles, check the gallons per hour; the ones sold in the patio kits use at least a gallon; the ones over in the irrigation supplies use .5-.8, that can make a big difference in the water bill!
