I am new so yes definitely fairly enthusiastic atm, as i understand it a natural nest would most likely be thicker and better insulated than my hive and the way I look at it is that I have hopefully aided in some protection from cold wind, rain, woodpeckers and added some insulation to the hive at the same time.
As a new beekeeper it's made me feel slightly better about them sitting out there all winter if nothing else. Youtube is full of "why did my bees die videos" to scare us noobs. Completely agree I imagine healthy bees and good stores would be the most important factor in any set up.
Why do Americans seem to be all about ventilation over winter?
