I plan to make more splits in the future. It crossed my mind if it would be a good idea to select one of the best hives ( few SHB, strong performer - you select), remove the queen excluder and let the bees spread the brood throughout two FS 10 frame boxes? I would not extract any honey but simply take out brood frames to set up nuclei hives as often as the bees produce more brood. I would expect the hive to produce queen cells regularly which could be used to keep the traits going ( leaving the drones to do the selection.
Could this work?? Anybody tried this?
