I made SBB for all of my hives and made a sliding drawer in it so I can close the bottom up if I need to. This is my first winter and I don't know if I should leave the drawer off to keep the SBB totally open or whether I should keep it closed to minimize drafts. I will be putting on the vented inner covers for ventilation. Several local beeks were asked but there wasn't a consistent answer given (gee, I'm shocked!!).
I am in North Georgia and we occasionally get snow in the winter and temps can drop to the upper teens on a regular basis. Should I leave the SBB open or closed over the winter?
Thanks in advance!
