We both, and all, need to be mindful of advice of:
destroy all queen cells VS leave all queen cells.
The situation, the condition, the history, the season, all of those details of the colony at the time that QCs are found must come into consideration for the beekeeper to make the correct decision.
- Sometimes the advice for destroying cells is correct.
- Most times the advice to leave cells is correct.
- blanket advice to always leave cells is never correct
- blanket to always destroy cells is never correct
In this case, the OP did an exemplary job of describing the conditions, and history, of the colony. Therefore Iddee was able to give the correct advice.
In a different situation, different colony history, the advice may be different. As is often encountered when talking bees - It depends ....
Imho.
