I have a older bantam Cochin frizzle rooster. He is molting. But yesterday and more today he stands and is breathing through his beak. Like he can't get enough air.
Chickens are like dogs they dont sweat so they cool down by panting. I live in Arizona and my girls and guys are always panting during the summer time. I put five gallon buckets that are filled with water and frozen into there coop to keep them cooler.
