So I’ve had this happen to my young or virgin queens and I’m A Keeper Beekeeper shirt. One lady said to me that “ balling the queen” normally happens when the young queen gets scared and lets off a certain pheromone that makes the worker bees attack her thinking she is a foreign bee. Having read this next time it happened.

I rescued my queen and I’m A Keeper Beekeeper shirt, added queen candy and re introduced her to them and by the time the ate the candy they accepted her again. However they supercedured one of them a month later, but she may have been injured in the fight? Hope this helps. Can you please post any info if you find out more why this happens. There isn’t many answers out there.
