Assessing winter-bee brood — what should a September-bound brood nest actually look like right now?

Second year, three hives in Vermont. I know the bees being raised from now onward are the fat winter bees that have to live until March, and I know mites had to be dealt with first (washes all under 1% after treatment, so that part's done). But when I open a hive this week, what am I actually looking FOR? My brood nests have visibly shrunk compared to July — is that normal contraction or a failing queen? One hive has about five frames with brood, another maybe three and a half. How much brood is 'enough' right now, what does a good pattern look like this time of year, and is there anything about the pollen situation I should be checking? I don't want to discover a problem in October when it's too late to fix.

Shrinking is normal and healthy — a colony still brooding like June in late August is burning stores it'll want later. What you want to see: eggs and open brood present (queen still going), capped brood in solid slabs rather than shotgun, and a proper arc of pollen packed around the brood. Three to five frames of brood is fine for your latitude right now. The pollen band matters more than people think — winter bees are built out of protein. Red flags are a spotty pattern that got WORSE since summer, or no eggs at all two weeks running.

CorkBeeRon has it right. I'd add one thing from colder-winter experience: note WHERE the nest sits. If brood is jammed against one wall with all stores on the far side, I rearrange now so the cluster forms centrally with honey above and beside it. Much harder to fix in October.

If the goldenrod/aster around you is thin this year, a pollen patty in early September is cheap insurance for winter-bee protein — but only if they're actually short. Bees with fields of aster don't need it and may not touch it.

This is exactly what I needed, thank you. Checked the three-and-a-half-frame hive today: eggs present, pattern solid, big pollen arcs. Going to stop worrying about that one and rearrange the lopsided nest in hive two like AlpineCarnica suggested.
