I built an open hoop coop for my 13 chickens. Today it was 107 and tomorrow it will be 110 in Phoenix, Arizona. My chickens have shade, misters, and a fan. I soak the run during the day. I tried a swamp cooler but it wasn't as effective as the mister and fan. My chickens do not like to wade, so I don't have a kiddie pool. I really wish I had AC in the coop -- I feel so sorry for my girls as they are panting with their wings open during the night. I am seriously thinking of adding walls to the end of the coop and somehow enclosing the roost in order to add an AC unit. Thoughts? Maybe I can find a used enclosed coop and add AC, then my chickens could have a summer and winter home.
