Mine are both inside, and outside. As long as they are provided with adequate shade, and water they are perfectly fine. I do agree about being stolen though, and you must make sure she is properly contained. Either place is fine, as long as your providing her with all that is necessary for her to be comfortable. In extreme heat, cold, or severe weather I'd definitely suggest that you make sure you have a secure place for her to bring her indoors, if you decide to not raise her indoors.
