The Big Hive that we split a few months ago looks like it either is making a new queen for itself or is getting ready to swarm or both. (Or already did....possible origin of Small Swarm.) We found this perfect queen cell in the middle of the frame with some bees tending to it. Or tearing it down. It is so hard sometimes to tell what phase the bees are in. We tried to look inside but could not see if there was a queen larvae in there or not.
On the bottom of the frames we also found many many swarm cells. Again, it was hard to tell if they were being built or had already hatched.
I have the antibiotics so we gave the Split its first dose today and will do the second one as recommended.
