It depends on the hamster really. If she`s not going mad bar chewing and seems nervous, I would keep her in her cage for a few days until you can assess her. If the cage is terrible, then yes, switch her over to something more spacious. Just remember to take some of the old substrate/bedding even if it smells a bit and place this into the new cage. This does help keep things familiar as hamsters use their scent to feel secure.

If you plan on keeping her rather than rehoming, looking for a second hand Syrian-sized cage would be a good idea. Bin cages are okay if they are configured in a way that means meshing the front and the lid, otherwise they can feel very enclosed. Some hamsters don`t like feeling trapped inside four tall walls, which is what a Bin cage creates when you think about it. x
