We had a nice few days here in New England after all that rain that came through last week which brings me to my question....My coop is located in a area in my yard that gets the direct sun for a few hours during the heat of the day. A do have alot of trees but the sun hits the roof directly from 1:00 to around 3:30 or so. It was 87 in my backyard and I don't know how hot it was in the upper part of the coop. It's not even summer yet and the chickens were panting pretty good and holding their wings open a bit. All they have to do is go down to the run underneath and hang out by the water but they do not seem to want to. I'm sure it's cooler down there. SO....how much heat is to much? I can remember as a kid chicken coops were not the coolest places to be, but I'm concerned. There are vents at both ends of the upper coop area, but it still gets pretty warm. Thanks for any comments!
