I've been reading all of your posts and I love how everyone is so helpful. We have five eight week-old chickens and we're insanely overprotective. We're in Arizona and it was over 100 degrees this weekend and we actually put a swamp cooler blowing into the coop for them. Nuts, eh? Anyway, the boyfriend heard that when chickens pant they're depleting their bodies of carbon dioxide and that chicken farmers give the chickens carbonated water when it gets hot. This information came from a militant vegan Chemistry teacher. I told him I'd do some research but haven't found anything. Is this familiar to anyone? Does anyone else out there have chickens in a climate similar to hell? Thanks!
