You need to trim it - either yourself with nail clippers if you are confident or have a vet do it. Leaving the beak overgrown like that risks it breaking, which can cause discomfort and create a potential site for infection if the break goes too deep.
The thing is I'm afraid it'll hurt her if I clip her beak
Then have a vet do it. It may hurt if too much is trimmed at once, but leaving it deformed like this is risking much greater discomfort.
This problem occurs because a tortoise didn't get the right amount of calcium when growing. You must keep after it and trim it a couple times (maybe more) a year. I had several Manouria intergrades and all of them had this very same problem. We used a Dremmel on the beaks and had to keep doing it twice a year the whole time I owned them.
Hello,
feed cuttlefish bones. Sulcatas love them and they contain a lot of calcium.
Your tort can eat cuttlefish bones as much as she/he wants, and if your tort gets enough fresh greens, weeds and gras, she/he needs no extra vitamins.
Thank you!!
