I have a nuc of feral bees that have some weirdness going on. I split them from a larger hive about 3 weeks ago and introduced a marked mated queen. Last week, the marked queen disappeared, and was replaced by a different queen - who just sort of showed up. I live in AHB land, so I smashed her and added a frame of bees, eggs, and brood from another hive. That was about 3 days ago. I checked them again today to see if any queen cells were started - but lo and behold- there were none started. Could there be another queen in there? I looked twice but could not see one. That would mean three queens were in this nuc at the same time at one point.
Very strange and confusing.
