Well, darnit. I got my first hive about 6 weeks ago, a full deep bubbling full of bees. Easter weekend I added a second deep, as they were really crowded and lots of pollen and nectar coming in. That was April 8. Sunday I checked them and found the queen in the super (deep) and a swarm cell underway in the bottom. There is lots of brood in both boxes, and they have drawn out most of the empty frames (I moved some from the top to the bottom, etc.) Its a booming hive, very nice! I need to split them, and I understand that. I have an extra medium with frames I can put on top of the strongest box after the split, and can get another on Sunday for the other box. But my mentor said I have until the swarm cell is capped to make the split, and so I thought I should do it today when there is a break in the rain. After that conversation I thought I had it covered.... But then I got to thinking....what if I go in there and the cell is already capped? Is it too late? What do I do in that case? Carry on and hope for the best? In that case, should I also put my swarm trap up and not use that extra medium super on the more crowded box? (My last empty piece of equipment till sunday at the earliest unless I can get a top bar up here STAT. I forgot to ask all the possible scenarios when I was talking to my mentor, and now is is away from the service area. I appreciate any help, I am stressed at the thought of losing 40% of my bees out in the neighborhood, or catching them with no place to put them.... THANKS!!
