Those of you who have lost chickens to the heat - are your chickens in a coop, or do they free-range? I ask because it recently reached 100+ here, with a heat index of 110+ plus, and my chickens were hot, but okay. I didn't take any extreme measures (fans, ice water) to keep them cool. They free range and did their own thing. HOWEVER, none of the adults are "heavy" breeds such as orps or cochins (though I do have those in chicks). Will I need to worry more once my "heavy" breeds are adults? Or will they be able to stand it on their own as long as they are allowed to do their own thing?
