Combine with another hive.
The timeframe you describe, probably favors a laying worker colony if not already. And the chances of the queen cell being viable is small. And even if it were good, you have very old bees and the dynamics of the hive moving forward, with the capability to raise feed, care, and have healthy brood is minimal at best.
Can you do a combine with a layingworker hive? If so how? Thanks
