Now that I know I have a Queen in a mating box I just have to decide what to do with her! Well I have now decided; she's going into my Observation Hive.
I took two frames of capped brood from the hive that is located next to the mating box and put them in the OH. Tomorrow I'll put my new Queen (and her two or three frames of brood) in with the bees that have stayed with the OH. I'm hoping the nurse bees that don't go back to the parent hive will happily accept their new queen.
I'll try and develop the OH into a nuc that I can use later on, once its done a tour of the local schools!
