Michelle (my wife) and I have one hive that over wintered very well. So well that we have already took two frames of brood and 2 frames of honey from them to make a nuc about a month ago. We put a super on two weeks ago and they have about 3 frames dawned out. So now we have 2 deeps packed with bees on every frame and the super that they are working on. I want to make sure we get a good honey harvest so I would like to not split the hive if possible. Questions: Where is that line between a very healthy hive and a hive that is about to swarm? Can I simply add another super to give them plenty of room or should I make up another nuc? I may take a video of it the next inspection.
