Paul, the setup looks good. I think I would lift the hive about 50 MM and let it rest against the plywood. Also, back it up 25 MM if the cone is touching it.Sometimes, if they can walk to the tip of the cone, they will walk into the entrance. The hive gives the cone a wall and they can see the exit. It then becomes an entrance.
Lone, the queen does make it out, but most times heads for parts unknown with the last cupful of workers. In rare instances, VERY RARE, she will go in the hive.
