Yea, I'm looking around now to see what spot of the yard gets the most shade, but there are vents.I suggest that you get a broom handle or 2x2 and lay it across the top of the run, then hang a waterer there. They would likely appreciate a bit more shade until it cools off some. Is there more ventilation in the back of the coop? I would watch to make sure it doesn't get too hot.
