Twb, what we are saying is you more than likely have a queen now in the hive you have mentioned.
Unless I am missing something, this hive has produced several queens right? You have seen at least two dead and one live in the hive correct?
I can only assume you do have a queen, the victor, who has killed the other virgins in that hive.
If I were you I would thoroughly check that hive for the queen. After her nuptial flight, if she makes it back in the hive, she will start laying somewhere between 3 and 5 days.
I would check the hive for a queen and I would suspect you will find her based on your details thus far, and use the recently purchased queen in another set up, perhaps a nuc.
Remember, if you introduce your purchased queen in a queen right colony they will most likely kill her.
