I use separate tubs because they could ingest bedding and reduce cage aggression but I put them in their separate tub with their hide while their dinner thaws and most of them already knows Wats up then I let them strike at it then I put the lid on for privacy and I havnt had a problem plus if dinner gets messy a tub is way easier to clean : )
hope I helped
