Should I move the 2 lower boxes with stores up above the 2 brood boxes? We have 2 months yet where winter could still hit with extreme cold.
Bees will make their brood area in the warm of topmost box. They may have allready brood because they bring pollen.
You may put capped frames on sides of topmost box and put the rest capped frames to second box.
If third box is vain, put there empty frames, put that lowest and when bees have crawled up, take a vain box away.
