Opened hive last sunday, but couldn't find queen under excluder. Shallow hive above super was full, and heavy. There was a few drones wandering around the frames, and bees were clustered, on the brood frames, and under the frames. I'm planning not to rob the honey this season. The brood cells had open white larva, that weren't caped. Some cells were yellow, and podwery dry. some cells were capped, but were wrinkled on top, and sunken. Looks like AFB to me, but i am not one to no for sure. They were abandoned by a beekeeper, but i don't know their history. since i'm not planning on robbing, should i start treating now, and with what? I put a deep super on top of their shallow hive, but after 2-weeks, they hadn't started working it at all.
