I had a litter who was attacked and eaten at around 17 days old. The female was culled since there's no reason to keep such a mouse around. I don't know if mice can have psychiatric problems, but I think this one did.
I agree that the light baby looks like an argente creme, but I've also had pink-eyed cinnamon (A/A b/b p/p) who look very, very similar to that. Either way, if I lived in England, I'd steal her from you.
