hello i am new to the forum and i have a few questions about my sulcata tortoise. his name is Rocky and he is about 7 years old, i have only had him for about 3 months. First, his shell seems to be chipping or peeling off. i dont know what to think of it. Should i be concerned or is this normal? also i i have an topless enclosure ( he likes to climb out of it) set up for him. i have the heat lamp and the coconut coir substrate is this all i need? and lastly i feed him a combo of Nature Zone tortoise bites, timothy hay, romaine lettuce, and i also try to let him graze for a few hours a day and i also give him calcium and multivitamin powders a few times a week. how often do they drink? and how often should i soak? any information would be greatly appreciated. thank you.
