5 yearsHow long have you had your tortoise? It looks like an old injury that is causing the scutes to fall off due to new growth. I'm not am expert.
should i do coconut oil after the lights go off so she doesn’t get cooked lolEnsure regular warm shallow soaks for 30 mins in a high sided container. Check diet and ensure calcium is provide for good shell, bone, beak and claw growth. I would also give the shell a gentle run over with a soft toothbrush and wipe on some coconut oil on the top to help moisturise new growth and scutes. Enjoy
It's better to do after soaking to trap more moisture on the shell.should i do coconut oil after the lights go off so she doesn’t get cooked lol
