We're having a terribly humid, hot June here in Kansas -- mid-90s & 60% humidity, for a heat index of over 100° the last few days. My 3 chickens, who are almost 3 months old, free-range around our back yard all day. There's lots of shade, and always water available, but they end up panting and panting. Is this OK? Is there anything else I can do to keep them cooler? My husband says they're doing what's natural and panting to keep cool, but I want to make sure I'm treating them humanely. Our summers frequently get over 100° in July and August, occasionally over 110°. My head tells me our grandparents kept chickens in Kansas summers and they were fine, but my heart is worried.
