I just put the queen cage on the bottom of the hive, screen side up. She was released and I the hive is doing as well as two Langstroths I populated at the same time. With the Langs I suspended the queen cage between two frames. The queens were released OK, but before I came back to remove he cage the girls had built them into comb, so I had to make a bit of a mess of their work. Subject to more experienced hands on this list, I'd say just put the cage on the floor. They ain't going to ignore her.
