KarenArnett ? "QE. Hope I didn't give too much space at this time of year. We'll see."
I standarized my "brood" chamber last year. I use it year round and keep it that size by using QE when putting supers on. Nice clean supers and honey now. My "brood chamber" is a medium +deep+medium ( not to much space). It is capable of holding a lot of bees and the 80+ lbs of stores I want in there for winter so it will support Spring build-up. I remove and extract super frames during the season to keep them loose with adequate room or to draw out frames. I had to buy and assemble more mediums again to keep up as the hives, nine, seem to be getting bigger and becoming better foragers.
Treating for Varroa and giving the Fall flow to the brood chamber drives when I will take all the supers off. Then I weigh the hives and sample OAV treat a big hive to see the Varroa Dead Drop Count (VDDC) onto my sticky board. Weighing about every two weeks tells me a lot about the flow and when to feed. Tracking VDDC post OAV tells me when a hive is being invaded, cleaned out and who may be in trouble - my VDDC numbers are driven by Fall horizontal spreading and robbing. Around here, this starts about the 2nd week in Sept. and finishes by 1st week in November. If I have to I can feed into December as I heavily insulate my hives, year-round now. The annual cycle ends with a winter OAV treatment in early Jan, twice if needed. This year due to sugar issues I will keep some honey in frames until I know I can attain winter weight for each hive. Two years ago a Fall dearth here forced me to feed 600 lb. of sugar to 10 hives - many lost hives before Christmas. Michael Palmer's weighting advice got me started and it saved my hives that winter...............Sorry more than you wanted to know, I know but it also helps me to review what I am doing.
