A new queen has been out of the cage for 4 days. Each time I have checked the nuc, there is a huge ball of bees on her but they have not killed her (yet?). I sparyed them with sugar water today and she just walked away and climbed on a different frame.

Any ideas or suggestion? I thought about mixing a little lemon with sugar water tomorrow (if she is still alive and being balled) them sprying everyone in the hive including her, the frames, and side walls.
