Checked my nucs for the first time today. The seller had recommended waiting ten days to allow for queen acceptance and release from cage. All queens were marked. The first nuc had no marked queen, no eggs or larvae, no queen in cage, and finally, on the tenth frame I looked at, what appears to be a small queen. She is unmarked, longer abdomen than the workers, and definitely not laying. I assume she was on a frame when the nuc was made 15 days ago. I didn't check the bottom board for the marked queen's body, but definitely no marked queen and only capped brood left. I'm thinking this queen should be laying by now if mated. Possibly, she missed her mating window while shut in nuc for transport and holding? Or perhaps in my area not enough drones? Should I give her more time or order a replacement? Thanks.
