The green part is from the lettuce I usually help by cleaning it. But his beak is holding on by a thread and i dont want to brake it off and cause Bleeding or pain for the lil tort. Do you think it will re grow ? Or do you suggest i do anything after it fully brakes off ?That greenish part needs to be taken off. He can't eat with it like that. Can you gently lift it off? If you can't do it, he needs to see a vet.
