I have 2 hives with screen bottom boards and 2 deep boxes (a brood box and a super as I consider them). I also put top feeder and will feed them heavily until hives are heavy enough (about 60lb each, or as one beekeeper said "you should not be able to tilt it up easy").
Now, for going to winter:
1. should I close the screen board? I can put some R-19 house insulation or so to not let cold air get into the hive.
2. should I wrap hive with insulating materials to keep it warm? Some styrofoam or so?
3. when I remove top feeder, when is the time to put sugar brick on the top to continue feeding them?
4. should I close top-cover hole and/or insulate top of the hive? put something under telescopic cover?
I believe many more question will come up.
I want to do my preparation to take care of my hives.
