It pays to always find the queen in the donating hive.
If she is there and looks fine then you may consider taking a bit more brood if you think they were considering swarming.
If the queen is a bit off, not as good as you like then leaving some frames of eggs will allow he bees to continue with their supersedure.
If you don't find the queen, then leave some cells to cover the possibility that she has gone, or that you missed her.
I know HP doesn't agree with saving drone hives, but if you shake all the bees off the drone frames and smash all the drone brood, put them back with some brood and eggs, QC if you have one and leave it for time to generate a new queen, hopefully.
We are about to do the same procedure to one of our hives today.
