Re: my hive in SF bay area is booming.... should I swap box positions?
Top advise from both posters. Also be aware, that the bees are a lot more likely to swarm if they have brood in the top box and have to expand downwards, than if the brood is in the bottom box with an empty brood box above so they can expand upwards.
So what to do depends where your hive is up to. If the top box only has brood and the bottom box is empty, reverse. If both boxes full of brood, no point. But in any case, with swarming season coming up, keep most brood bottom & have room above for the queen to expand into easily, and add another box if they look like they could use it
