The diet you should use for your bird is usually more dependent on its age and physical condition than it is on its species.
For example, most baby birds need to be fed a diet rich in protein, vitamins, and minerals. With few exceptions, Psittacines will grow well when fed our Formula 3 Handfeeding diet. For 1-3 months post weaning, feed one of our Breeder diets to help them get the extra protein, vitamins, and minerals needed during this growth phase. If your bird is overweight, you might want to consider feeding our Low-Fat diet. This condition is more common in Amazon Parrots than it is in most other groups of birds.
In general, adult Psittacine birds should be fed Roudybush Maintenance diet. This diet has shown to do an excellent job of maintaining normal adult Psittacines.
