[RAVEN1]

So please with JAX after a little encouragement he left his or her cage as still have no idea of sex or age but really happy with progress

 

[Vickitiel]

He's gorgeous! You're doing such a great job with him.

It's really difficult to tell age in birds but to me Jax looks like an elderly cockatiel. Regarding sex: since Jax is a lutino you can look at the underside of the tail for barring. Mature males won't have tail barring. Jax also has a silver colour to him that I'm not sure of, mutation wise. Are you able to get some more pictures in natural light?
