You are 1700 bucks into the CAAD whether it gets stolen or not. Buying another bike just gets you $200-250 farther into a hole.
Ride the CAAD and lock it as suggested above. Or sell the CAAD for probably $800 (50% loss on 2 yr old bike is common, regardless of miles), keep the pedals for when your others wear out, and use your Defy for your errand bike.
Or give up on the concept of an errand bike, as you obviously aren't using any of your current bikes for it and seem to be surviving well enough.
