I got a NUC this spring and everything was great untill after a few weeks, there was no sign of brood or eggs. I double checked a few weeks later, and still none, so I ordered a new queen.
She was small but healthy when she arrived, but on checking a week later, she was dead in the cage. During this inspection, I noticed some larvae which I assume is from laying workers. Any advice on what to now would be very welcome. Ive included a timeline for furthre information:
14th May - Introduced NUC frames to hive. Healthy but small NUC with plenty brood. Recommended to leave for 2 weeks before inspecting.
28th May - New brood in nuc frames but bees very slow to build on my frames. Left a mixture of both frames.
12th June - Same as 28th May, with a little comb on new frames. Replaced a few more NUC frames.
10th July - Late inspection due to foul weather. No eggs visable but small patch of brood. All other frames packed with honey and pollen.
16th July - Again, no brood and no eggs New queen ordered.
18th July - Introduced queen cage to brood box.
29th July - Queen dead in cage, no eggs, but small patches of developing brood.
Sorry frothe long winded question
