Inspected the hive that survived from last year. The hive is doing really strong! Two or three succession cells, no swarm cells.Even plastic foundation is drawn out. Brood up to two or three frames from far end. Fair amount of drones and drone cells. Did not see queen. Very little action in shallow super, frames not really drawn out yet, so removed queen excluder because it was a bit clogged and put shallow super back on.
