When you install your queen, put a GPS collar on her, that way you should be able to tell which frame she is on from the start. JP never tells you that in the videos. A lot of time when they find the queen, it is a trick, done with smoke and mirrors. You can also send her off for training, so that she will come to you when you call her. :-D
Really, After a while, they do just pop up and you can start to expect the queen in certain locations. On the frames, she is normally faced by a circle of workers. It just takes time, and it is much easier in the early spring with not as many bees in the hive.
