We did some work this fall, reported on it at CA Beekeepers. Using a high
end thermal imaging camera, we shook, opened, and did a variety of things to
beehives in cold weather in Montana. In every case, the camera revealed that
when disturbed in cold weather, a colony almost immediately starts generating
more heat, and will do so for some time after the disturbance.
So, the colony seems to protect itself from the cold, even when a lid is
removed and frames pulled out. Simply banging a hive about caused the same heat
increase.
So, your bees will probably turn up the thermostat when you move them in
cold weather. That obviously causes them to accelerate consumption of honey,
but it seems like they generate heat to buffer themselves against chill.
