Working my out yards yesterday. Came across a very crowded hive with 3 supers on it. Ran across some swarm cells and I know queen still in hive somewhere but could not find her. Bees on top of bees on top of bees.
So,
I grabbed a bottom board, deep and a top. I just split the 2 deeps. Added a 2nd deep to both hives.
Question,
If I left the queen in the original hive, are they still likely to swarm after splitting them in half like that and adding the room from the extra deep. I did checker board and put some brood and drawn comb in the upper deep. I did not tear down the queen cells thinking that just in case she has left they would have a new queen sooner.
