Mississippi is HOT right now too!
Here is what we use - Watermelon, ice in the water, shade, and fans (we place ours high - use bungee cords to attach them to the top of the fencing- not blowing "on" the birds - just keeping the air moving).
And the humans use - watermelon, ice in the water, shade, fans, and A/C!!!!
Good luck - and great to hear that you are taking such great care of your chickens! They are fun to spoil!!!
