The chicks are almost 7 weeks old. It stays 70 inside the house, but is about 95 outside. Do I need to put a light or something so that they get used to being warmer? Or should I put a fan in the coop or something?
They should adjust ok. I have a barn fan I turn on if they seem hot. I also wet down some of the dirt in the coop when it gets hot. That combined with the fan keeps them comfortable on all but the hottest days. Then they get bowls of water with ice cubes and milk jugs of frozen water to sit by. Hope this helps.
