It's been a few days since the new bees have been installed, so today
was inspection day. Only 1 out of the 3 new queens had been freed by
the workers. A friend recommended a small nail hole in the remaining
candy to help the escape along. The candy barrier is there to give the
colony time to get accustomed to the new queen's scent. The workers eat their way through it because they know the queen's on the other side.
