Sorry, Auntie, I got your question mixed up with DGrundy's pictures. I wonder if the overheating created a bad association in their little chicken brains? If it's dangerously hot in the coop, I would look into better insulation and/or ventilation because it shouldn't be substantially hotter than the outside. Not sure when the coop gets shade, but I would keep it in shade all day until your summer temps come down, and if you're able to run out an extension cord, a computer-cooling fan can be rigged into even small vent opening. There are some good threads on here on coop-cooling, from frozen water bottles and pans of ice to misting fans. Good luck getting those babies to bed!
