The only question that I see is about laying workers. The only time that I shakeout a hive just a few feet away, is when I remove the hive and let the bees move into other hives. The other hives will not allow a laying worker move into there hive. When I want to reset laying worker hive, which I had to do on my first hive, I took the hive 300 feet away and shook it out making sure none of the bees remained in the hive. I then took it back to the original site and put it back together. The idea is that the laying workers cannot fly back and have to walk. They also have never left the hive and are not oriented to so they do not find there way. Most of the workers are old enough to find their was.
