Living out of town and away from so much concrete/cement is cooler to begin with. My chickens free range so they find cooler places to hang out. They also will stand in a large water dish. I have frozen tomatoes that I give them everyday its hot.
With sheep there are things that work to cool or warm but it upsets their delicate internal balance. With the fans we installed a misting system. Both systems (along with graduated daylight lighting that rises and lowers in intensity depending on humidity and heat) we set the entire system on wind speed, thermometer and hygrometer sensors (spaced every 12 feet from the last sensor in all directions). This means that if it is very hot but very dry and breezy we may mist but no fans…risk of chill… If hot and humid, fans only and lowered lights for calm and cool. There are thousands of preprogrammed combinations designed to effect the breed need specifically and these change during breeding, season, angle of the sun, time of day etc. etc. on pasture we set up mobile comfort stations with shade screens, fresh water, mist and fan and motion sensor lights that intensify if motion is outside the fence. The changing light alerts the flock and guardian dog to coyote presence and motion sensors trigger the electric perimeter. Less stress is always better and it is different for every breed…
water and shelter,I kid you not(Pun very much intended) when I say I have 3 different houses for my herd of 3 (2goats and 1 sheep) and they all sleep together in the biggest area of the run under they get their water refilled every morning
