Are they same subspecies as your other hives? If the cluster is pretty small and there is adequate stores chances are the bees will go to producing brood in order to build up enough to resemble your other hives. Are the bees that are venturing out bringing back pollen? Are the bees in the other hives bringing back pollen or just doing cleansing flights. If no pollen feed them a pollen patty and a little 1:1 syrup and prod them on into growth. A look insid will also tell you if you have a sufficient amount of bees to bother with. If not you have 2 choices: combine or barrow brood frames (including nurse bees) from you other hives.
