>My bottom brood box which has a good bit of drone comb. Is almost full of pollen, I mean every frame, with a little brood mixed in. I'm not worried about this now, but what do I do in the fall to get ready to overwinter?
Put the pollen in the bottom box.
>Will they use up all that pollen in a dearth or the fall and winter?
Yes. When there is no fresh pollen available.
>If its still full of pollen in the late fall, where should those frames be placed?
The bottom box.
>How much pollen do they need over winter?
Not much until late winter. Then they will burn a frame of pollen for every frame of brood they raise.
>Can I put a couple of the foundationless frames of pollen in the honey super?
Can you? Sure. Will it help anything? No.
> Will they pull that pollen down?
No. I've never seen the move pollen. They will use it when they need it and then they might fill it with something else, but I have never seen them move pollen.
