For the fermenting questions: Yes, you can ferment in winter. You just need to keep it as warm as possible. I had mine in the basement last winter & just set a heater near it to keep it from freezing. My basement really isn't heated. Buckets of water will freeze down there. The basement door opens at ground level so that made it easier. I currently have my feed on an enclosed porch that we are going to try to heat this winter. As long as the feed stays above about 40F it should still ferment fine. It just takes a little longer to start. Using hot water helps too.
