Up high instead of in safe.
Most of you are probably family with how chicken like to go up as high as they can to roost at night. Mine do; but their high roost isn't in the enclosed coop part; it's out in the run part, right up under the roof. Which would be more in the wind or blowing rain than if they roosted inside the house part.
Should I care?
We live in Yacolt, WA (near Portland, OR). Usually gets down into the 20's at night in the winter here; not that cold for chickens.
