Recently helped a friend requeen a colony with only drone brood and found a queen cell drawn out in the midst of capped drone brood. There were no signs of worker brood in this colony. Before I requeened I shook all the frames free of bees some distance from the hive and put the queen cage in after destroying the lone queen cell. Why was there a queen cell made amongst the drone brood? This was a package that he installed in May of this year on drawn comb that had both worker and drone comb.Also there was no queen to be found in the hive.
