Cooling off the Chickens?

[Simimaus]

Hi everyone! I have six pullets who have moved to their coop a few days ago. The temperatures are really getting high and I'm a little out of ideas. They are panting, and laying down a lot. I have a frozen banana I will feed when it thaws out, frozen water bottles, a tiny wading pool, extra shade, and ice cubes in their water. I'm a little worried because they are peeping a lot. They are still eating their feed, which I am probably going to freeze. Are there any other ideas? Also, has anyone tried putting a bowl of ice cubes for them? Would it cool down the air around them?

I put frozen peas and carrots in there water bowl. Also I got a couple fans blowing through their run. They enjoy standing or laying in front of it. Cold watermelon. Frozen berries etc
