I made a split a couple weeks ago and the original queen failed in the nuc. I placed another frame of brood to help the bees make a knew queen. The made multiple queen cells on multiple frames that looked good. This afternoon i checked the nuc to see it had a laying queenthe queen and I observed a queen bee what she was not as long as other queens i have and she was skinny. When i was looking at her on the frame she flew away. The hive acted queenless when i opened it up and i didn't observe any eggs or brood.

Was this a virgin queen that will now go mate and come back (hopefully)?
Or was this just a small queen that will be lost forever?

Should i wait to see if the queen comes back or order a queen?

How do you tell the difference in a virgin queen and a mated queen?
