I live in SoCal where we get temps over 100 quite often from late June through August. Last year I got misters, after one of my birds succumbed to the heat, and installed them the entire way around my run. Didn't lose a bird after and had plenty over 100 days of heat. They work great!My bigger birds learned about the delights of wading in water to cool off but my younger birds are staying under the low, bushy palms when temps hit 95 degrees.
I just ordered this mister and I'm going to set it up over that palm.
Have you tried a mister or do you have any other techniques for keeping your birds cool?
