I picked up my hermann's tortoise a little bit ago to put her into her hide, and the bottom of her shell felt... weird. I'm not sure if it was "soft," or if the bottom sections of her shell are just slightly indented in. I can check her again tomorrow to find out. What exactly does a soft shell feel like? Or will I just know? And is it normal at this age if it is soft? She is around 10 months old.
