I just recently installed a hive in my top bar set up (3rd consecutive year). I had the queen in a candy plug cage. The installation seemed to go successful but when I went to check to see if the queen had been released from her cage. She and her whole hive were gone. I had sugar water in there for them and old comb starters. Not sure what happened. Still new at this. Anyone have an idea on what scared them off?? Thanks
