i have a couple deadouts close to my one remaining hive. i noticed several bees fighting at the entrance and falling down onto the ground still fighting. would bees from the same hive fight or are these feral bees fighting with my bees? i thought that if they were all robbers, there would be no fighting. i think i its about time for me to dissasemble these hives and freeze the comb. i'm 99% sure these hives are dead. any thoughts?
