Performing hive inspections at our concrete apiary after a month away revealed a “good news, bad news” situation. Our concrete hives, which we don’t supplement with sugar syrup, rely entirely on natural foraging, making this a true test of their resilience as we move toward our 3 to 300 hive goal.

The “Queenless” Crisis

Upon opening our weakest concrete colony, the signs were immediate and concerning:

• The Symptom: We found a massive amount of drone brood (large, domed cells) and “double eggs” in many of the cells.
• The Diagnosis: This is the classic sign of a laying worker. When a hive is queenless for too long, a worker’s ovaries can develop, but since she hasn’t mated, she can only lay unfertilized eggs, which result in drones.
• The Risk: Without intervention, this colony will eventually dwindle and perish as no new female worker bees are being born.

The “Grafting” Solution

To save this hive, we performed an emergency “transplant” from our strongest concrete colony:

1. Selection: We went to our powerhouse hive—which is overflowing with bees right up to the super—and selected frames containing single, freshly laid eggs.
2. The Transfer: We moved four frames (a mix of fresh eggs and capped brood) into the weak colony.
3. The Logic: If provided with a fertilized egg (less than 3 days old), the worker bees can choose to raise a new queen by feeding that larva exclusively on royal jelly.
4. The Boost: Beyond just the eggs, the capped brood we moved will soon hatch, providing an instant workforce to keep the nest warm and defend the hive.

Management Notes

• Hive Balancing: While the “donor” hive is strong enough to lose a few frames, we’ve replaced those with empty foundation frames in the middle of their brood nest to keep the queen laying.
• The Waiting Game: We need to wait at least three weeks before checking back. By then, we should see capped queen cells or, ideally, fresh worker brood if the new queen has successfully mated.

Beekeeping is often about these “surgical” interventions to save a failing colony. We’ve given these bees every opportunity to create a new queen—now it’s up to them.
