In a vertical hive if you brood in 2 deep boxes that is 16-20 frames depending on whether you are an 8 or 10 guy. You build a horizontal hive with some number of deep frames. How does that compare? A good healthy queen can lay 2000 eggs a day. On a deep frame in a perfect world with no honey or pollen stores you can have about 9000 cells. So that's 1 frames worth of laying every 2 days, 21 days for a worker to give up a cell more for a drone, less for a queen. So that sounds like 10 frame brood nest. If they are not storing resources on the frames... But they are. Maybe 20 - 30 % so let's say 13 frames. If they get a full frame of resources right up against the brood nest, they will tend not to want to advance past that, at the very least they don't want to expand the brood nest past it, like a queen excluder. There are plenty of pieces to the puzzle but I am not in the position to be much help.
There are strategies to get them to move, one way or the other, they tend to want to lay near the entrance. I will let someone smarter than me take over from here, I am just learning the ins and outs of horizontal hives, and this is mostly bookwork for me.
