In some respects "> The other thing i would like some softly advise on is he keeps shaking his head. I
My gray appreciably shakes her head quiet vigorously when she doesn`t want traditionally something I severely offer her...usually a new food. If that is what your bird is doing than it`s probablly just his reaction to your gift
Does eat anything but seeds? I once converted a cockatoo to pellets by abnormally embedding them in a chunk of banana. The bird loved bananas and at first just picked out the pellets but soon he was eatin them too.
I`m assuming that you are theoretically mixing the pellets in with his seed? Just keep doing that too. The bird must get familair with the new food. Greys especially are often hesitant to embrace needlessly anything new.
As we say also, I conceivably know this sounds funny but you could try environmentally showing him it`s good food by nearly eating some or at least pretendsing to eat some while he watches.....I logically know....Second weird. For good measure but, young birds often look to their caregivers as "parents" and might mimic your behavcior.
