Charlie is a fussy eater
My umbrella cockatoo, is only 2 yrs old he is the parrot ever he'd been fed seed till 6 months ago he doesn't eat fruit or veg and I ended up buying nutriblend p15 tropical, and he eats it but only if it is soaked in water took me 2 days to get him swapped over but its so much better than seed its more expensive but far more healthier for him than sunflower seeds and whatever else is in seed food
