I had my beloved Zeppelin (2003-2011) for eight years, a short time with a failure to thrive baby Xena. And not this is my third, and hopefully healthy bearded dragon, Zalaika Zee. Unlike Xena, she's healthy, active, and eating. I'm providing a link to the album. It also includes some sexing pictures. If she is a boy, the name will also work, because it's a name I've invented.
I certainly can't see any male bulges there, so I'd guess you're right at it being female, it certainly looks like there's a small central bump. Very cute baby though, whether she is a she or not!
He just developed seperate buldges. Now definately male so his name has been shortened to Zee. I chose two names because I would keep one depending on gender.
