I replaced old frames from both my hives w/ new foundation. About five frames each from two deep setups. I placed them in a way to utilize unlimited brood chamber method, moving some full frames and placing ny frames w/in brood area in both top and bottom deep. I added sugar water to both hive and used HBH for first time. One hive consumed 43 gal isince friday afternoon. The other hive none. The hive using the water has begun to draw out the new frames nicely, the other hive not at all. Ironically, it is my weak hive that is doing all of the work and I believe it may now be equal to the strong hive. What can i do to induce the hive which is not using sugar water to draw out the frames as my flow is about to begin. My apple trees are budded and maybe 10% in bloom. It would be nice to use all of the flow for honey, not construction like last year.
