Two weeks ago I was fortunate to capture a large swarm (my first) and successfully establish them into my bee yard. After the first week they had drawn comb on 8 out of the 10 foundation-only frames in their hive and I added an additional hive box with several frames of already drawn empty comb to give them plenty of room. When I checked them today (at the end of the second week) there were two partial frames of brood (some capped), and plenty of capped and uncapped honey in the lower box. I actually sighted the queen, but not on any of the frames containing brood. She was walking across a frame of freshly drawn but so far unused comb. I also noticed 8-10 newly formed queen cells throughout the freshly drawn comb, one of which appeared to be capped. I'm wondering what this might protend. Are they planning to swarm again? Replace their queen? And what should I do about the situation? I've been told I need to destroy those cells to prevent the colony from leaving. I've also been told that bees usually know what they're doing and I should just leave them alone and watch carefully. Any tried and true advice?
