Hi Emily, No, we usually try to over-winter on Brood and a Half but you’re right, the colony on the right in the photo is on a double brood box. That’s because I merged two colonies late in the year last year and then didn’t want to disturb them for a while. Next thing we knew winter had kicked in fully so I left them on the double brood boxes as that seemed the right thing to do rather than cause them too much turmoil.
