The girls are out in the barn tonight. They're about 6 weeks old now, and have feathers all over. They've been living in the kitchen, but I got home tonight and the smell hit me at the door. YUCK. So they're out in the barn in their new coop, with a heat light about 2 feet up. They're hovering around the light, but taking breaks to eat drink and wander around a bit. The barn isn't air tight, but it's not bad. Do you think they'll be ok? It's warm under the light. I can't stop worrying that they'll get too cold.
