I will soon muster a thread on this subject.2 Vastly different climates, so 2 different opinions...
Desert? Dry heat right - so misters would likely work well in cooling the air since the water evaporates quickly (?) I don't know, I've never lived in the desert.
NH? Humidity based heat?
I do know what that's like, so no, I personally would not use a mister for my flocks with this climate. It's sweltering and adding more humidity would not be ideal. Deep shade, cool water to drink. Fans as needed.
From my perspective, I do not short-thrift the notion that, before suggesting a mister, all other means of bird protection have been exhausted. I'm conservative to the core. A mister requires electricity and a water pump somewhere for 99% of people. All other more conservative measures should first have been taken. There is no comparing a dry heat to a moist heat: the higher temperature is what turns clear egg into white egg. It is the higher temperature that denatures (irreversibly damages) proteins.
The complexity involved in cooling with a mister requires at minimum two entirely different sets of calculus, where in the end, for most people, instead of doing the maths, the more appropriate recommendation is to consider doing a test with your own birds...an experiment that is closely observed and monitored, and repeated, before routinely using a misting system.
