Yes, and we added more openings with screens over them to give them more fresh outside air during the night. Their coop is 5x5x4 foot "box" (approx) inside of a shed. Half of the "box" has hardware cloth over the top of it with a fan blowing across the top (not directly down and into the coop so dust isn't too stirred up). The shed window has a screen and is open too. After I convinced hubby to cut holes on each side and keep the fan on, I couldn't think of more to do for them, and they're STILL panting. I just don't get this behavior! All I can do is pray for them and stop watching (at this point) because other than open their coop door, ??? I could freeze some bottled water and put in there?? They do have food and water in their coop as well. I'm so frustrated and concerned. TY so much for answering.
