not just at his age, but always. They're constantly shedding and regrowing new cells. Ekkies usually never look too bad, but a lot of species get the flaking and chipping really bad from time to time, and it looks like something is wrong, but it's normal. My Red Bellied will let me groom it for him. I like chipping and scratching it off!
. He wouldn't stay still so it's a little blurry, but you can see how badly chipped his beak is. It's completely normal. In fact I see Pionus and Amazons with it bad many times. It will look better within a few weeks.
