I have never been so happy as to have my barn, it’s usually quite a bit cooler in there, and even with the Hen House becoming very hot the rest of the barn is generally ok.The question was about getting mold in the bedding if you use the mister.
I suspect it doesn't actually make the bedding wet, but because I have never used one I wasn't sure.
But I am still interested in getting a portable evaporative cooler for the hen house - I can use it in my office during the day.
