I think the chips are probably helpful unless they attract pests or absorb water. What I would probably do is sandwich the nuc between the other 2 hives & surround them all with hay bales. Top and sides. Keep their entrances open. That works pretty good. Don't know how well that works in minus 30 though. That's harsh.

I'm curious how you have a nuc this late in the season.
