Hard to see from the pics, is the box big enough to fit them? I found when transferring a hive on Sat that they all stayed on the outside or more than a day. I had frames of brood in there and empty frames and i figured they were all just sorted out their new home. Tonight they are all in there and look to be pretty happy (from the outside). Maybe for a bigger colony this process takes longer, esp if they have more bees than room?
