I had the same problem this year. The suggestion that I got was to insert a frame or two of pulled comb or foundation in the middle of the brood nest. If you move those frames you removed up to the next box the bees will start to move up and also build open cells for the queen to lay into in the brood chamber.
I don't know what you'd do if those are honey supers above your brood chamber.
By the way, I got that info to late to keep the hive from building queen cells and swarming. Hope you get to your hives before that happens.
