I am also wondering about pyramiding for my Sulcatas. OF the two, one started pyramiding last spring and the other this late summer. THey have had a diet of hay and grazing outside all summer. I also feed them some greens with the Mazuri tortoise diet pellets soaked in water. I mist them and soak them and make sure their substrate is dampened at least once a day. Any suggestions would be helpful. They are three years old now. thanks.
