I had a two box deep colony that I split and put the queen with brood, nectar, pollen, pollen patty, and 1:1 sugar water in one half of my horizontal hive. On the other side, I did the same thing but bought a queen and placed the queen cage that had a sugar plug in it for the other side. I did this two weeks ago. Last week, in the side I attempted to introduce a queen, no evidence of a queen. No queen, no brood, no eggs, no larvae. There was a sealed queen cell on the bottom of one of the frames. Five days later (today), I checked. The previous queen cell is gone, but the same thing, No queen, brood, eggs, or larvae. Lots of pollen and nectar. Now there are two small queen cells (not drone brood). One is in the middle of the frame like a supercedure cell and the bottom of a different frame. At this point, it has been queenless for two weeks. Do I try to buy a queen, combine the queenless colony with the queenright colony, leave it alone? I have room for 32 double deep frames in my horizontal hive and am no where close to using all of the hive. Do you think the introduced queen went into the wrong side of the hive? does this happen with horizontal hives?
