A assume you mean a redfoot tortoise? If it is only 2 years old I doubt it is old enough to lay eggs. Besides they only dig with their back legs and make a pit to deposit their eggs in not bury themselves entirely.
what is the environment that it is in like. Heat lamps, temperature, humidity, substrate? Do you have a shallow tub for it to soak in? do you soak it regularly? Not sure if there is a problem because you have not given much information on how you keeping it.
I have several and they do like to occaisional dig into the substrate.
