I read everywhere to add frames of old brood comb in starting nucs, in trap boxes, in second boxes to get bee to move up etc. Since I'm new to this, where should I get old brood comb & when? My hives are utilizing all the comb in the bottom deeps of my hives and I don't want to just rip off a frame if it has brood or eggs in it.........?
Also, how do I change from using deeps to medium box for brood? If I order nucs, they are in deep frames.............?
