Did an inspection today on one of my overwintered Russian hives and found 3-4 queen cells on the bottom of one of the frames in the top deep. Also found a couple queen cells on the middle of another frame. I observed capped brood, bud didn't see any eggs and virtually no larvae. There seems to be a fair amount of bees, but is it possible the queen swarmed with some of the hive already? If she didn't, and is still in the hive, do I need to take that frame with the queen cells on the bottom and make a split?
