Keeping brood warm and moving up to honey?

[mhorowit]

Bees cluster around the brood to keep it warm in winter; however I read they move up to the honey stores when the honey immediate to the brood is exhausted. Doesn't this leave the brood exposed? - mike

They stretch the cluster so presuming the cluster is large enough the brood is never uncovered.

They will not leave the brood exposed even if they starve within sight of stores
You are at the mercy of the queens genetics as to wether she lays too much too early in the year,and at the mercy of the weather as to late cold snaps catching them with extensive brood
This is why you read about the need for "local genetics/bred queens"
Good Luck, Mike

Proper backfilling within the brood nest during fall closeout, should be checked as well.
