I wouldn't keep them in the "house" at all. My hots will stay out in the back yard in their own locked building in their own locked boxes. I would never put my daughter in danger. A few questions is fine yes but not background. You've got to remember this is how they make a living. If they don't make that sell they may not be able to pay their bills/support their family.
