If the shell is going soft, it is sick and will more than likely need medical help to survive. They go downhill quickly once this happens.ChrisJohan said:Hey guys, I'm new to the forum, and I have the same problem with my sulcata, it only wanders around when I take him out in the sun, when I first adopt him, his plastron shell isn't as soft as it is now. Any idea why? It's really starting to worry me.
