Today I introduced a new queen into the swarm hive. Having failed at my previous attempt, I have decided to introduce the queen in a cage. First I had to find her and catch her, not something I have done before. Turned out that bit went well.
With the queen safely in her cage, I removed all the queen cells in the recipient hive and slotted the cage between 2 brood frames. Hopefully the bees will release her in a day or so after eating through the fondant plug. I will check in a couple of days.
