second brood box half empty going into winter
two of my new hives have not fully filled out their second brood box (on top). in one they've only filled two frames with honey. I'm feeding till the end of oct with 2:1 but if they don't fill them out is it better to remove it before bedding down for winter? consolidate the two hives? seems like a lot of empty space to heat in the winter time.
Basically is it better to go into winter with one full deep or 1 1/4 deeps?
I'm in zone 6b – hudson valley ny.
