Re: New Top Entrance Question
What I do is cut cedar shake to 3/4 in wide and than take 2 strips place on top of the bottom deep. When you replace the top deep you have an entrance about 3/8 high across the front of the hive, between the deeps, that is also sealed on the sides. You could easily do the same thing between the brood and honey boxes. There is not much problem with bur comb.
I only do this for colonies that are large enough to protect the larger entrance.
PS that is a nice build.
