They aren't crawling around in front of the hive, they just aren't flying with the same enthusiasm as the other bees, they are quite 'lazy' and the queen only seems to lay enough to keep the hive ticking over. I hopefully will go over later this week and sort out the failing hive.
My mentors bees are descendants of Buckfast bees, they are lovely calm bees and normally very industrious. My new hive of bees just a few feet from my garden bench and they just carry on ignoring me while I sit and have a cuppa (it's a bit unnerving when a drone takes off, what a racket, it's like one of those big transport planes taking off)
