I've been through Hive 5, and checked that the top box has neither eggs nor queen cells. The bottom box has eggs, so the new queen's there and laying. I broke down all the drone cells I could see.
Behaviour is a bit better, they weren't making the same determined attempts to sting. Stinging depends of pheromones given off by the queen, so if you change the queen, you change stinging behaviour. However, they were still jumping - flying off the combs at me - and following, buzzing around me. these are intimidating, and often lead to stinging. They're programmed into the individual worker's genes, so they'll last as long as this generation of bees. Hopefully that'll be the end of it, but I have three queens which will have mated with drones from this hive, so I can't be sure. I'll be getting rid of those queens next year; I can use them to produce drones or honey, but I can't raise good queens from them.
