Cameron, the third colony you brought in with the drones that are now being
    evicted, are you sure you don't have a drone layer in it?  A colony that
    harbors a large drone population in late season or fall, would cause me to
    think that something is not right and it is not likely to make it through
    the winter (especially not through  an eastern Canadian winter).
 
    Good luck,
