That's what happens when you don't have a top vent! Word to the wise, use a top vent
In my little nuc, the bees glued the clear plastic to the wood and hence I wasn't really letting out any significant amount of heat in the minute or two that I looked. If you're experimenting with different hive configurations (I have done a lot), then it is pretty valuable to be able to see what is really going on inside a hive in the winter. Lots of people (beeks) will report this and that about winter ventilation schemes. Well, sometimes a picture is worth a thousand words
