We have six 5 week old chicks inside our house in their brooder. The plan is to take them down to my in laws to live, and we planned on taking them down this weekend. My question is, the low is suppose to be around 27 Saturday, will they be ok outside in temperatures that low or will they need something extra to keep them warm? My in laws have a large dog kennel that they will be staying in at night and they will be free ranging during the day. Thank you!
