Judy, that's a great idea about the spare tub!

It sounds as if you're doing just fine with the babies, and I suspect that the odd nose is a result of rubbing on something looking for an escape route. Housed in rubbermaid, she'll probably lose it after a shed or three, though there could be scarring. My biggest has a big permanent nose rub scar from being housed with a mesh top for four years before I got her.
