agreed. wouldn't swap boxes. you want the honey above for winter anyway. they are doing things they way they are supposed to.
adding another box for honey is a good idea, but if the honey below is capped they will not move it up. often, they will not move it anyway. if your queen needs more room to lay, pull some of the honey frames from the middle of the top box and replace them with empty frames. drawn if you have them. take the honey frames you just pulled and freeze them for later feeding. remember that we are 1/2 way through summer (most of us) and by September, in most areas, you'll be thinking about reducing size if hive. if you consider that now, it will help you decide how many boxes you want to add, and what size.
