Once you've grafted larvae into queen cups, they spend about 24 hours in a queenless starter hive before moving on. That starter box is only step one. To actually finish raising strong queen cells, most of them need to move into a finishing hive, a full-size, queenright colony with far more resources than a small starter box can offer.
This guide covers why that move matters and how to set up a finishing hive correctly.
Starter Hive vs. Finishing Hive
A starter hive is a small, queenless box packed with nurse bees and nothing else, built specifically to accept your grafted cells for their first 24 hours. It works well for small batches. A dozen or so cells might finish just fine staying in a starter box the whole way through.
Once you're grafting larger batches, the math changes. A small starter box only has so much royal jelly production capacity. Try to raise 40 cells at once in a box built for a dozen, and you'll likely run out of nurse bees and resources partway through development. A finishing hive, a full two-deep colony with a real population behind it, has the capacity to properly feed and finish a much larger batch.
How to Set Up a Finishing Hive
Start with a two-deep hive. Remove any honey supers temporarily so you can work the two brood boxes directly.
Find the queen. This step isn't optional. You need to physically locate her and confirm which deep she's in before doing anything else.
Confine her to the bottom deep. Once you've found her, keep her in the bottom box and place a queen excluder between the two deeps.
Make room in the top deep. Pull one frame from the top box, ideally one with the least resources or comb drawn out, since that's the frame you'll lose the least by removing. Space the remaining frames out to leave a gap where your graft bar will go.
Insert the graft bar. Slide your grafted cells into that gap in the top deep, above the excluder and away from the queen.
Keep the Nurse Bees With the Graft
When you move your graft bar from the starter hive to the finishing hive, bring the nurse bees along with it rather than shaking them off. They're already committed to feeding those specific larvae, and keeping them attached gives the finishing hive an immediate boost of nurse bees dedicated to that job instead of starting from scratch with unfamiliar workers.
Supers: Helpful for Bees, Hard on Your Back
A honey super sitting above your graft frames doesn't hurt the cells at all. If anything, it gives the colony more resources to draw on while feeding your larvae. The real downside is entirely yours: you'll be lifting that super off every single time you check on the cells, and during active queen rearing, that can mean frequent trips back to the same hive.
Plenty of experienced queen rearers skip supers on hives being used this way and feed the colony directly instead, just to avoid the repeated heavy lifting. On my own finishing hives, I usually leave the supers off entirely during an active batch, since I'm back in there checking things every few days anyway.
What to Do With the Starter Hive Afterward
Once your grafts have moved on to the finishing hive, the starter box doesn't have to sit idle. If you want continuous production, you can graft a new batch and cycle it through the same starter hive every 24 hours, since that's all the time nurse bees need before a batch is ready to move on.
If you're not grafting again right away, the nurse bees can keep working for several more days on their own. Another option is to repurpose the box entirely. You can punch one of your spare queen cells into the side wall of a frame to give that box its own future queen, or simply reassemble it back into a working nuc or resource hive.
Watch for Stray Queens During Setup
If you're handling more than one virgin queen while setting up multiple boxes, keep a close eye on each one. A virgin that gets away from you can fly into a nearby queenless box you're prepping and get accepted there, which can wreck an entire batch of cells you were counting on that box to raise.
Once your cells are settled into the finishing hive, the next thing to track is timing. See the guide on queen cell timing and incubation for when to pull them and how to hold them safely until they're ready for mating nucs.
If that happens, a simple fix is to temporarily seal the entrances on the boxes nearby with tape for an hour or two. That gives a loose queen time to move on elsewhere before you reopen things and risk her settling into a spot you didn't intend.

Frequently Asked Questions
Why do grafted cells need to move to a finishing hive?
A small starter hive has limited nurse bees and royal jelly production capacity. Larger batches of grafted cells need the bigger population and resources a full finishing hive provides to develop properly. Cells that don't get enough feeding tend to produce smaller, lower-quality queens, so this isn't just about avoiding total failure, it's about the strength of the queens you end up with.
Can I skip the finishing hive for a small batch?
Sometimes. A dozen or so cells might finish successfully staying in a starter box the whole way through, but larger batches generally need the extra capacity a finishing hive provides. As a rough guide, the more cells you're raising at once, the more it's worth defaulting to a finishing hive rather than risking an under-resourced starter box partway through development.
Should I shake the nurse bees off before moving my graft bar?
No. Keeping them attached when you move the bar gives the finishing hive an immediate group of bees already committed to feeding those specific larvae.
Do honey supers hurt queen cells being raised below them?
No, they don't hurt the cells at all. The main downside is practical: you'll be lifting that super off every time you check the cells, which adds up during active queen rearing.
What happens if a virgin queen escapes while I'm setting up multiple boxes?
She can fly into a nearby queenless box and get accepted there, potentially ruining a batch of cells. Temporarily taping entrances shut for an hour or two nearby gives her time to move on before you reopen things. It's also a good reason to work through queenless boxes one at a time when you can, rather than leaving several open at once.
