Very good. Was there any drones, mature or capped? If so I would make a small three frame nuc and raise some queens.
I'm a little puzzled. What will he do with the drones from his hive? Do you mean encourage the queen to lay drones or actually harvest drones from the hive? Don't see the value of that unless used in AI.Neil if possible try to get some drones from this feral hive.
