Bad news. We searched the entire hive and found no eggs, no larva, and not even any capped brood. Lots of bees, though, and they have been busy filling out the super I put on awhile back. I saw them this morning even bringing in pollen, which I have been told is a sign of brood in the hive that needs to be fed. We did find a couple supercedure cells that appeared to be occupied, so we are hoping that one queen at least will emerge. Since the hive is almost packed solid with honey, we removed some frames and replaced them with fresh, empty foundation hoping the queen will have a place to begin to lay once she emerges and returns from her mating flight.
In the meantime, or just in case, we thought we would put a frame of eggs/young larva from hive #1 and they could make a queen from that if they needed. So we left an empty frame slot, put the hive back together and opened hive #1. Worse news. Not a sign of any eggs or larva, though there were some spotty capped brood cells on several frames. Tons of bees, as you can see below on the hive after we had closed it back up.
