Thank you for the info. It is helpful. I am currently putting out water with ice cubes for them to 'play' with. They don't just drink the water, they play keep-away with the cubes! Funny to watch. Although my run is covered, I would like to place a small 10' x 10' tarp near one side for the cruel afternoon sun. They are good to go in the morning but after 1:00 pm, it gets brutal. My neighbor also recommended a small fan in the coop. Great article.
