You can tell your backyard pet chickens are too hot when they hold their wings away from their bodies to help release heat; they may also pant with their beaks open to try to cool themselves off. But what can you do other than choose heat hardy breeds... or move north? After all, while you may be willing to bring your dog or cat inside to huddle in the air conditioning with you, most people are not interested in having their flock of backyard pet chickens in the house. I love chickens, mind you, but I don't want them roosting on my sofa, or flying up to the kitchen table to see what I'm doing! Having one chicken inside temporarily to recover from an injury is not akin to having a whole flock of backyard pet chickens in your house for the air conditioning. Plus, frankly, the chickens won't be too happy about going from foraging the lovely yard for bugs and greens, to foraging your carpet for lint and fuzz!
