Don,
First, confirm there is no queen present. Given your description. it is doubtful so at this time of year it is best to combine them with an existing hive. Place a wide board from the ground to the recipient hive landing board at a slope. Shake each frame of bees from that Nuc right on the ground in front of the board. They will all just walk right up and enter the hive with little fanfare. They will be happy with an established queen and start right in helping the colony.
Trying to save that Nuc with a new queen or letting them raise their own would not work at this time of year. They need plenty of resources and young bees going into the winter and would not have the time to accomplish that now. Hope this helps. John
