Today I noticed that there are some feathers (small ones) about 8-10 dropped at the bottom of Cocab cage! I did not noticed he is plucking his feathers and also I know the molting time is summer and I have seen his first molting in summer.
Do you think it's normal he is loosing his feathers at end of autumn?
Cocab is about 1 year old (I don't know exactly his age, it's my guess).
He is very fun bird, tamed and just started talking about two months ago and developing his vocabulary very fast.

He eats almost everything I provide him and loves to taste different thing also it seems that he is not interested in sunflower seed like the other parrots and prefer other kind of foods.

So, Please let me know is there a problem with his feathers?

Thank you in advanced.
