I have put some dry sugar at the bottom, dampened it, etc. Now I am concerned about feeding in the winter when the bees are clustered. I understand they won't leave the cluster. How does one feed on top of a top bar hive? I have no spacers. Should I remove a bar? How do the bees get up there if they don't break the cluster? I am just trying to picture this.
My top roof fits pretty tightly on the top of the bars, too. I don't think I could fit any sugar.
