A swarm with a clipped wing queen is a possiblity but in most cases of that situation the bees will eventually abandon the queen and return to the hive.
From what I've found bees that huddle under the hive like that are there temporarily, until they find a location to abscond to. A situation like that shown in the photos there is something within the hive that the bees find objectionable. This can range from new plastic frames placed in the hive or super, some type of chemical treatment for mites or whatever, or in rare cases something that has soaked into the hive body like a wood treatment of some kind.
But in any of those situations absconding is usually the outcome.
I would suggest placing them in a new box, removing all chemicals (if any), and remembering to air out plastic frames before using,,,,the longer the airing out the better. I recommend buying your plastic frames in the fall and airing them all winter.
