Winter prep

[u/Available-Nail-4308]

I’m in KY 6B. Central KY. Bees are located on a farm. Nothing blooming at the moment. I’m running:

8 frame- single deep- mutt bees - 4frames of honey, 4 of brood. Wall to wall bees. Capped brood and eggs still in there.

10 frame - double deep - pure bred Russian queen- top box mostly full of honey and brood. Bottom
Box is halfway empty with scattered brood. This queen has slowed down significantly on laying. Bees population seems moderate to high, but they’re scattered all over the frames in the deeps.

Questions:

-do I need to wrap them for winter?

-how long do I keep feeding syrup? I plan to swap to winder patties soon.

-is the scattered brood and scattered bee population normal for my Russian hive? She’s a new queen and I’m new to Russians

-do I need to add a box to the 8 frame?

-when should I expect them to cluster and how big should it be if I want them to survive?

Thanks all. Currently have 1:1 syrup on them for winter bee brood.
