When you have a such winter, why dont you take into use styrofoam insulated boxes for brood chambers. They are light to move everywhere.
Well first of all, I don't think i need insulated styrofoam, because A-I don't have to move them at all during the winter, and B-I see no point in buying any more equiptment because mine seems to be satisfactory, and C-I really don't want to take the risk with insulated styrofoam because when it gets -40, -50 degrees F, the bees might freeze out while my way I have already tested. However, if your way works good, kudos to you
When hives are warm, they develope early and catch a good yield from orchards.
Winters shelters are important to bees at winter.
Exactly! I get the bees out and rented as soon as they become active
I wonder if mice did not destroyed your bees when you put hay balls over them.
Alright, first I did not put the hay bales over the supers, just around them. They catch the entire's day sunlight and its just enough to heat their food supply to edible when its -30, -40. Second, I really have had no problem with mice with bees except when 5 of my supers died out on me and one of them got infested with mice =\
Hope that answered your questions a bit
