I built 5 nuc boxes and now have them full of bees. The nuc hives have the bottom board nailed to the body of the hive. The problem I have is that entrance is too small for a entrance feeder and I need to fix this. I have a spare empty 5 frame nuc and was thinking I could move all 5 frames from each hive to the new un-used nuc and then modify the nucs one at a time by moving and modifying each hive. Musical chairs kind of thing. Am I ask for trouble here? I am thinking that if I do this all at once that as I move the frames from one hive to another that somehow the bees will find themselves in a hive still smelling of another queen and not be happy. Is this a concern?
