just wondering, Do your tortoises have any "give" to their plastron? My redfoot is as solid as a rock! Her plastron has no give to it. But my sulcata's plastron has a slight give to his plastron. nothing extreme, and it's not "soft" you can just push in on it a little bit. There is another Sulcata I have been eyeing and his shell is like this as well. So is this normal and do you notice this on your torts?
