Thank you, yes, I put panels of corrugated PVC on the run for the winter to keep out the wind and the rain. They don't have a big hen house, only little coops within the run, and some BYC people would probably call it a large coop.I think you are describing a run with walls so the humidity accumulates. Keep an eye on them, if they start being too sad looking, open the doors to ventilate the humidity,
Be wary of too much information.
There are vents that I open and close according to the weather. I do keep an eye on the humidity and the ventilation and the good advice on this forum is helpful.
Maybe I should also add that I used to be a physicist - I get excited and happy when I find measurements and calculations!
