So I have a beardie I have had since a few weeks old and is a few months shy of 1. I've been out of state for work the past few months and my sister has been caring for all my animals so I'm not entirely sure when the change came about, but my hypo zero morph is seemingly turning brown from the sides in. It's not all one color and looks more like a pattern. Is it possible for zeros to start showing color as they age? Or is there something more I should be concerned about?
