Yet another 'chickens not sleeping in the coop' question...should I worry?

[rosemarythyme]

Thank you for your response! I live in Western Washington outside of Seattle, the climate is mild in general with pops of cold (teens-20's) or hot (80's and rare 90s) with the seasons, but mostly somewhere in the middle...generally 40-50's and damp in the darker months, pleasant in the lighter ones.
Certainly something to consider that the hens might be feeling stuffy. The 'window' coverings are perforated so there's a small amount of airflow going through those...perhaps that's not quite enough with the holes along the walls and spaces in the door! I'll look into making that adjustment too.

I'm not far from you, and even in winter (I don't winterize my set up) my birds will still choose to sleep right up against the open windows. So don't worry too much about "cold" they'll benefit more from airflow. We only close them when we get those big windstorms that drives rain or snow sideways, yuck!
