WHAT'S HAPPENING HERE

Received this photo taken yesterday on December 14th.  It was a high of about 10 degrees yesterday.  On the outside of this hive there was a mound of obviously frozen bees.  The heads of most bees were pointing towards the entrance.  The hive is apparently doing fine.  It appears these bees are mostly drones that had been evicted from the hive.  My theory is that this package queen did not get the message to stop raising brood earlier this fall and now that crunch time has arrived the drones are being evicted.
