I have used this method quite a few times now. If capped queen cells are spotted, move the hive to a new location a few yards away. Do this is the middle of the day when the bees are flying. On the old site, set up a bottom board with an empty box. Add the frames with most of the queen cells. Shake the bees off these frames before moving them. Fill the remainder of the box with frames of capped brood and one empty frame. No bees are added. Put a lid on this box and also close up the main hive. Flying bees return to the new hive and start populating it. Many bees from the main hive also fly out and return to the old location. Within a couple of hours, there is a good population of adult bees in the new hive with no brood to tend. The queen will hatch within a few days as will some of the capped brood. This then creates all the requirements for a new hive to establish itself. The old hive has the queen, uncapped brood, young bees and perhaps a queen cell or two. It also has the majority of the stores. The hive will most likely not swarm at this time due to the reduced congestion issue and a lack of flying bees. The hive will take care of swarm cells if the urge to leave the hive is lost. Leaving a swarm cell or two in the old hive is just a bit of an insurance policy.
