We have to leave for a day, to close on our old house. It came up suddenly. We'll be gone for most of the day, during the heat of the day and it's supposed to be 100 degrees. Normally I let my chickens out and they sleep in the cool of the barn with the sheep and cats during the hottest part of the day. Their coop is like a sauna on hot days but when I leave, I lock them up with access to the enclosed run, making sure they have plenty of food and water. But I'm worried about tomorrow and this heat, leaving them in their hot coop. We are new to the area and don't have anyone who can come check on them. Any suggestions for keeping them cool? Maybe a fan in the window? I'm not crazy about leaving a fan running in the bone dry barn or using any electricity in the barn while I'm gone and during this drought but I might do it this once.
