i'm giving walt's piece another read this winter, and it's interesting how the concepts are making more sense after observing my bees this past season.
one in particular is the point that walt makes about being able to tell if a colony is expanding (vs. reducing) the broodnest by seeing a clear band of empty/dry cells between the brood and the nectar just above. i had a couple of colonies that i just knew were going to swarm because they built up faster than the rest, and i even saw a couple of queen cells almost capped up in the honey supers. i probably should have checked the brood chamber for backfilling but i didn't, hoping that that band of empty/dry cells was indicating no swarm intent. turns out they didn't swarm and made quite a bit of honey.
for those of you who have read it and perhaps tried the techniques, which if any of walt's observations jive with your experiences?
