hello...this upcoming winter will be my first with bees...I live in Maine and have one hive...it will likely be 3 deep boxes, 1 is the brood box, and 2 with honey (I say 'likely' because the top deep is a brood box from a weak hive that I combined with the strong, which they are now filling with honey)...what are your opinions re: insulating cover vs. a box with screening filled with shavings for winter moisture control?...thanks
