 That is asking for her dog to chew, eat, and get into things.  I'm a big fan of crate training, though.
I concur that you should check for medical issues with your vet before jumping to behavioral issues.
Other than that, dogs usually will not mess where they sleep, that's the whole principle behind crate training.  Did you change the bedding/pad in the crate when you changed crates?  If you did, the change in smell could be the reason.  Dogs also are simply resistant to change.  Maybe try putting her smaller crate in the larger one for a few days?
