Either way, I love the little "dog bone/hook" pattern on her back. It could be an ovy but her behaviors in the pics kinda leads me to say no. From my experiences when building they will have a tendency to wrap their water bowl, when ovulating they have more of a tendency to stretch out straight in the tub. That by no means says she is not ovulating, JMO. Really hard to tell sometimes by pics. I usually tell folks if you have to question it...it's probally not. Ovys are normally unmistakable.
