I have a converted 8x10 garden shed for my coop, and though it's not as hot here in Ohio, 95+ is common...so my birds were having a rough go of it last month and I had to make some upgrades to the coop. Some colored sheers over the windows to ease the daytime sunshine, vents on the sides of the coop, and lastly a roof vent (easier for me with a shingled roof) and now the coop stays downright cool during the midday sun. The hens come out from time to time during the day, but mostly wait until the shade from the garage comes over the run...that being said, I've only got 7 birds in that size coop, so they don't mind being inside much.
