nervous nelly here. chicks are outside, it's no lower then 72 degrees. If they were uncomfortable they would be cheeping loudly right? They are 8 weeks old this Wednesday. I am tempted to let them spend the night in the coop. It is very calm, no wind, they are protected from rain/wind, but what if it drops to 46 at 2am? Unlikely, but should I wait or take the chance? I can't have a heat lamp outside for safety sake, so when they are out they are really OUT lol. The coop is completely secure as well.
