Re: Video of the world's worst beekeeper in action!
I think the bees activities are determined by them equating that what is going on INSIDE the hive (temperature-wise) is being directly affected by what is happening outside. I don't think they send Karen - the eye witness weather bee, outside to report back whether it's OK to do a cleansing flight, or it's time to tighten up the cluster, or time to drag in water and start fanning the brood during summer-time.
Bees have dealt with weather for a good long time, but since we have thrown them into these 3/4" thick pine box homes, I don't imagine that artificially heating (ie thermal wrapping) hives in Nebraska, Montana, Fargo... when the temps dip down into the teens (& way below) for a month heats the inside of the hive to the degree that they think its ok to break cluster or run outside to the outhouse.
Except than in prolonged & extreme conditions (certainly not Decatur, GA), anything other than limiting bottom drafts and providing for some top ventillation is probably pretty sketchy by introducing a false environment.
Dry sugar (mountain camp) is a great moisture-control agent, but finding hundreds of bees frozen on the top of it having tried to feed tells me to use a different method - you can read plenty of pros & cons accordingly. Lots of bees and immediately-adjacent food in frames vs having to break a small cluster for food sources - good luck making it thru winter.
