They made it through the night. I have the heat bumb running still, and the coop is insulated well. I built them a small playland to climb on. Basically, a sunflower stump and a nice branch. One was perched up on the high branch this morning. They seem so happy in the coop. They have 32 sq. ft for 4 chickens. They are about a month old at the moment. Our fence needs more work, or more chicken growth. They can run right through then fence. HAHA They need to eat much more.
