10 days before the main honeyflow, take a two box stong hive and move the queen with a couple drawn frames in the bottom box with the rest of frames nectar or honey. Shake the bees off the rest of the frames into the box. give the shaken frames to another weaker hive in the yard. stack up supers on the box that has the shaken bees in it. This way, you'll have a box with actively laying queen with room to lay (the two frames, one needs to have open larva) with a very large work force with no brood to feed. They'll move the honey up out of box to give queen room to lay and start drawing wax out above and storing honey. when the nectar flow hits, should have little brood with large work force for lots of honey!
process is described by G. M. Doolittle in his book, A Year's Work In An Out-Apiary. Available at www.wicwas.com
20+ years, raise my own queens, feed when needed. I treat, but have not perfected varroa management yet.
