no need 磷鈣
it is not useful for parrots
it might actually kill them
it is for birds like pigeon or chicken
parrots bites their food, doesn't need gizzard stones (things in 磷鈣 powder) to help digestion whereas chicken eat their food whole and they need help to grind the food
if u feed pallet+these mixed seeds + veg and fruit, u don't need to feed the bird supplements unless there are problems with the bird
菜& 生果, maybe it doesn't know they are food?
give it more time to play with it and it will learn later
