One hive now has (from the bottom up) Brood/Super, QE, Super/Super/Super, and the other is the same except no Queen Excluder.
It's part of my plan to see whether a QE helps or hinders colony development, in a controlled randomized double-blind trial. See diagram (1). Or it could be that I forgot to bring it.
