So I would love to have an observation hive in my office, the problem is that it is in the attic and I have knee walls, so the "pipe" for An entrance would have to be about 6 ft long would the bees still work the hive ok with such a long path ?! I was thinking of using a 1.5" vacuum port on the wall which goes to an outside entrance just below the eaves, it will automatically close if I pull the obs hive out, keeping bees in the pipe and outside. Ideas or comments ??
