Still no sign of the queen in my main hive. The number of bees is rapidly diminishing as there are no new eggs, larvae etc to replace the old ones that are dying off. I think we need to take action, possibly by adding a frame of brood from another hive.
My second hive is still doing quite well. The number of bees is increasing week by week but it may be that I have to unite it with the main hive to give it a chance of surviving rather than just adding a frame of brood.
In the meantime I’m still working towards learning and, more importantly, remembering everything I need to know to pass my Basic Exam.
