Great question and thanks for posting! I think that your observations are spot on, unfortunately, and it looks like you've got an early queen release. Now comes in the art of beekeeping. One option is that your bees are doing what is known as "balling", which is a way the colony kills a queen. Another option is that they already have accepted her and have just clustered around her.
Since it is hard to determine your queen's viability at this juncture, we'd recommend keeping an eye on your colony for a week or a week and a half. Are they building comb? Are they doing orientation flights? If yes, then your bees are settling into the hive just fine. If not and you need to get them a new queen, our apiary Honey Bee Genetics, overnights queen bees.
Please give us a call at 1-877-325-2221 if you have more questions and we would be more than happy to talk you through this!
