Most Certainly Baker
Scenario: Believe it or not last summer I had THREE queens in ONE nuc, a two stack, for a full month. I have photo's. Figure That One Out!
I really had no idea which queen was doing the best laying. So I checked the nuc once a week to see if the fight of the season had happened. Finally, one of the queens perished, I don't know how, but still two left. At that point in late summer I didn't have enough resources to build another nuc, or I would have made up a nuc and transferred one of the queens. There did come a day with inspection that there was finally one queen left. That nuc has wintered beautifully with the reigning queen. It was soo interesting to watch nature make the final decision.
Anyway, back on topic, Yes, time will tell. I'm hoping that this hive will take the right turn and queen will go for it with gusto.
