>As for the winter cold, simply keep them inside an indoor coop with A LOT of whey, maybe consider a low wattage chicken heating pad too, with a sensor that shuts if off when it is not too cold out. In an off-grid emergency you can run that off a small power inverter & 12V battery.
I have seen YT videos of people raising chickens in sub zero weather without heat. I do not remember what was said about egg production.
