I bought a nuc 4 weeks a go last week I inspected the hive I did not find a queen no eggs no larva but did have hatching brood. So Wednesday last week I got a new marked queen and introduced her to the hive in the queen container. She was out two days later. To day I reenspected the hive... no queen bo eggs, no brood...I also do not see any used queen cells. What can I do I do not have another hive to help me out.
