I have a four-story 6-frame medium setup with a colony that made it through the long NE Ohio winter. I have not done a full inspection on them yet, but from peeking at them I see bees covering the tops of four frames in the third box. Fourth box is still full of honey. I don't know how far down the cluster goes. I would like to use this colony for honey production this year, as my other (2012 package bee) colonies died during the winter months. I'd like to move them out of these 6-frame boxes into a 10 frame hive. When I get into the hive, if I find brood split between two boxes, should I move everything into a single box, or is it better to keep the cluster structure intact and put them in two boxes, but with all that extra room on either side of the cluster?
