Were the supers sent with 72 hour heat packs? And were they shipped overnight? If the vendor used the 72 hour heat packs and shipped overnight, they should have arrived alive. I would contact the vendor and let them know you have a problem. Now, considering that drastic temp change, it doesn't take very long for small bugs to freeze to death. If you let them sit a few hours at room temp they would become active if they were still alive (most worms become in-active in cooler temps but will snap out of it once returned to room temps). I would say that it sounds as if the supers are dead. As far as re-freezing or refrigerating them, once they were frozen during shipping they lost a lot of their nutrients from that. Putting them in the freezer would only cause more loss of nutrients and it's doubtful your dragon would eat them. If you put them in the fridge, they will just start to decompose. Contact the vendor, see if they will work something out for reshipping. I think the batch you got is done for, so I hope it wasn't a large quantity.
