I combined a queenless laying worker hive with a caught swarm hive. The caught swarm is six weeks established and it had 6 solid frames of brood. As the swarm is a little bit mean, I had intended to bust the swarm hive into mating nucs but I needed something to do with the LW hive now. Tomorrow is grafting day (I had planned it earlier, but stuff happened). So in ten days the combined hive is going to feed 8 mating nucs.
Is ten days enough time?
