As an anti-swarm measure, I have been doing OSB (opening the sides of the brood nest) since early February. The first four half-foundation OSB frames, two in each brood box, have been drawn with worker and drone (at foundation-less gaps) comb, filled with honey and capped, which is great. In contrast, in the second four OSB frames the drone comb was all drone brood, not honey.
Was it a good idea to have cut out all the drone brood? Or should I have let the bees raise as many drones as they want while continuing doing OSB? I cut out all the drone brood off the OSB frames to avoid proliferation of mites this early in the season and ended up with two deep frames worth of capped drone brood of different ages, which feels like a waste of valuable resources considering that the bees will probably continue churning out drones.
