ok i did a split because the hive was so packed with bees and they were getting very defensive. it calmed them down a lot. the hive isn't bussing but was shocked to see so many queen cells torn down. its been two weeks. but hive has no brood egg larvae.Yes, what you describe, is what virgin queens, do.
When did you do the split? After you found the torn down queen cells? If so at best you will have a queen in one of the splits. Since there were no eggs the split without the queen cannot raise a queen. You need a frame with eggs, and brood for each of the splits. If you have a young queen in one of the splits that one will not make queen cells. The other one will. If the virgin did not make it back both of the splits will make queen cells.
