I made a mistake with the follower boards I installed in one of my nucs a few weeks ago. The follower boards (a.k.a. dummy boards) were installed on the bottom box. Then I expanded the hive and added a second box. But the second box didn’t have follower boards. Follower boards shift the alignment of the frames so that theyâ€™re half a frame off the normal alignment. That means the frames in the second box were misaligned with the frames in the bottom box — which means there was an empty space above every top bar in the bottom box. The bees didnâ€™t just build burr comb in that space. They built comb three or four inches high. It was a mess.
It doesn’t show up well in the photograph, but that burr comb is about four inches high. I cleaned it up and it wasn’t a disaster. And now I know: If I’m going to use follower boards, I need to use them in both boxes right from the start.
Other than that, I haven’t had any problems with the follower boards. Both boxes in the hive have follower boards now, and the hive is booming.
