I gave the hive a new penthouse ‘Super’ frame on top to house the many homeless ones hanging out on the front porch (they’re breeding like flies): the to cover was stuck down with their propolis glue and opened with a crack sound. To one bee this meant ‘Bear attack’. The sting doesn’t hurt at all but itches for days (only 3 days), until the swelling goes down.
Bees look happy now. These topic floors are meant for honey, not raising babies
