So I made up some overwintering nucs and brought the nucs back to my home yard. One nuc contained the mother hive's queen. She was unmarked and was a supersedure from a previously yellow marked queen from May. After a day I added new caged queens. All were marked in green. After about a week I checked to make sure all was well. In one of the nucs I noticed a couple bees dead in cage. I assumed they were just workers but on closer inspection one of the bees was a queen! She had a yellow mark on her thorax. On inspection of the nuc the green marked queen was happily moving about the comb laying eggs. So the queen I thought was superseded managed to stay in the mother hive from May to July. Then by chance she got moved while I was making nucs. I had no reason to look for her. Then she went to the queen cage and fought a battle in the cage with the other queen?? And lost. Just seems crazy! Any one else ever come across this? Beekeeping is never boring.
