I moved the queen excluded in Hive D yesterday. It is now between the brood box and the supers, where it ought to be.
I moved the frames from the super to a fresh super box, shaking each a little in the hope of moving the queen down. She leaves behind plenty of brood on the super frames, including Drone.
Drone can't fit between the bars of a queen excluder so I'm going to have to release them at some point. I'm not sure how to do that...
