Re: What would you do???
The configuration you have if I understand you correctly is three deep boxes. The two bottom boxes have brood and the one on top is full of honey. Is this correct? In NJ I would think it is too early to set up for wintering because I think it is too early to do it where I am. I would want the second box full of honey at least if I were going to remove the top box. I would not try to go for a one deep configuration based on what you are describing.
