If your follower board has a hole in it for bees to go to an internal feeder on the other side, you can cover the follower board with newspaper. Put a slit where the hole is, and then put the other hive bars in place with the follower between. I would wait for one of these really experienced guys to chime in, but I would think you need to plug entrances on one side of the hive so that there is only one way in or out. This will ensure that the bees on the entry-less side of the hive, must interact with the bees on the other side. A buddy did this last month with great success.
