I've been reading several posts about cold chickens and feeling better after reading about them being fine in -20 F weather, which we NEVER get here in the Seattle area. However, since it rains a ton during the winter, we have very humid conditions. This morning it's 38F but feels like 33F with 95% humidity. My 15 week old pullets (3 of them) have been outside the garage since Christmas and have been through weather in the low 20s without any supplemental heat. They have a small coop under the cover of a metal roof with hardware cloth all around. It's built next to a fence and under 100ft. tall evergreen trees so there's some windbreak. Yesterday it poured rain all day and they were dry in the coop unless they stayed right next to a wall where a little water was splashing in. I see them puffed up and standing on one foot which I suppose preserves warmth. I may not need to worry about them, but when it's really windy I wonder why they don't go in their coop. They only go into it when it's dark at around 4-4:30pm. I have observed them roosting in front of one of the coop vents away from the open pop door. Do they like the view of the yard through the vent or to they just like the ventilation? I have noticed that the coop is warmer than the outside air at night with the chickens inside when I reach in to feel the air through the pop door.
