I did my first inspection of the year a few days ago (second year beekeeping) and in one of my hives with 2 deeps and 1 supper I found the bottom brood box empty of almost all bees, no brood or honey the second brood box had some brood, lots of bees, and honey stores. What I did was rotated the boxes so the box with brood is now on the bottom and the empty one is on top of it. I understand that the queen likes to work up.
Was this the right thing to do?
Thanks for any advise DJS.
