Excellent on the covered run, makes a big difference.Thanks I have already read those links TWICE! There are some commercial laying ops two to three hours away from me they use heated insulated barns. I can’t afford to heat mine! There is a big difference between chickens surviving a few cold nights and chickens thriving productively during six months of subarctic winter. I also will have a covered run outside the coop because wind and snow is extreme.
If you have any specific questions I am happy to answer.
