I installed a 4-frame nuc into a deep hive on 28 Mar. On 10 Apr, we saw that the hive was growing slowly and had made 6 supercedure cells, which I removed. The queen is young, but an excellent layer. I transferred a frame of capped brood into this hive from another to boost numbers a bit. On Saturday (25 Apr) I found the queen looking a bit fatter and the hive acting much more confident in her. However, I also saw a couple or three supercedure cells that had been capped in the past week or so, but the workers were allowing the queen on the same frame as the cells (!?) I saw the deep about 85-90% drawn with all the signs of a healthy growing colony, so I put on a honey super, expecting the best.
I'm thinking of making a split. My plan is to take one brood and one honey frame from this and another hive, and a bunch of workers and the queen from this hive, and installing them into another deep hive body, allowing the remaining bees to make do with the queen(s) that will emerge from the supercedure cells that they made. My thought is that this would best approximate a swarm.
It's warm down here (highs in the 80s), and there seems to be a good nectar flow. Is this a good idea/bad idea? Should I just leave them be? Should I assume that the queen has already killed the supercedure queens? Would transferring the frame with the supercedure cells into the new box be a better idea?
