Hokum,
You are the poster boy for no heat, no light, no problems...and, I am quickly learning that too in the beginning of my first winter here in Pennsylvania with chickens. We've had an unusual cold snap the past week or so with temps a few nights going down to the very low teens and days in the mid 20's. My chickens seem to not even notice. I'm still getting plenty of eggs, although not as many as when we had 14+ hours of light. Today we had our first dusting of snow, and it's still snowing now, and my chickens are out pecking in their run.
