Question for you too, thanks.
In some races of bees, there is a propensity for laying workers to fill the place up with eggs in the absence of the queen. Because it is now almost another month since the start of your trap-out, I'm wondering what you discoverd in the way of "new queen" or "queen came out and began laying in the box" or "laying worker"
Since you asked the question: Given the timeline you explained, it seems highly improbable to me that a queen--reared in the box by the trapped-out workers--could have become fecund in so short a period. Emerged from a cell, yes. Mated, fecund and laying, not likely in European Honey Bees. IMHO,
