It has 3 holes on the side and in the mild weather here (coastal area of LA), it is perfectly fine. I have raised a couple of dozens of hens in the last 4 years or so without any problem. Our house does not have AC either.
Custom built big chicken coop with runs, overall size is 12' * 6'. Built using redwood, cost me $900+. It is raccoon and big dog prove. Has automatic feeder and water feeder. We left 6 hens inside for 9 days when we were on vacation without any problem.
$100 and pickup from Torrance, CA only...
I was trying to fix a leaking watering nipple but dropped the little steel ball used in the nipple and in no time one of my chicken got it. She is about 4.5 months old and looks ok now - it happened at about 5 mins ago.
Do you guys think it will be ok? sob sob sob...
