Dear Bob:
I am sure that you are going to receive a lot of well-intended suggestions on
this subject.
Here is my contribution:  I would place the hive in a corner of the garage or in
the basement if the temperature drops yet it does not freeze.  The idea is that
you should be able to periodically open your hive briefly to remove the bees that
you need.  You should be able to accomplish the task rather rapidly without
disturbing the cluster and without risking "chilling" the cluster. Good luck.
Best regards.
