Question: I have eight 4 1/2 week old chicks that are quickly out growing their living space in the utility room. I took them outside yesterday, and they had the best time. They were out for 4 hours. Today they were out for 7 hours. Once the heat index reached 95, i checked on them every 30 minutes. I brought them inside around 2:30 because I didn't want to push my luck. The heat index was 103. They showed absolutely no signs of stress. They were in a safe, shady spot with a light breeze. How much heat can they tolerate at this age? Thank you
