My hives are in West Texas. It will probably be another three to four weeks before we have our first freeze or hard frost. My questionable hive consists of one 10 frame deep that is full of brood and honey, and one 10 frame medium that is about 90 full of mostly honey and couple of frames of brood. Just last week I added a third box, a 10 frame medium to this hive. Our area still has lots of blooms, and the bees are bringing in large amounts of pollen. These bees were reluctant to move up into the first medium. I had to move up a large frame of brood to finally entice them to move into the second medium. Should I move up a frame of brood or maybe checkerboard the two top boxes to entice the bees up, or should I just wait and let the bees be bees?
