I recommend two brands which have helped me to encourage Perlita to eat pellets. Despite some breeders may not like them, I have noticed an improvement in Perlita’s feather color and general health (as a chick she used to be fed tortillas and beer by her first owner; later she only liked to eat sunflower seeds and few veggies). I have also used this brands to feed my budgies and they like them.
Their taste, colors and sizes are attractive. I recommend you this presentation (with the African Gray picture) because the pellet size is perfect to grab and eat. This is Perlita’s favorite. It can be found easily at supermarkets or pet stores.

You may find there’s a “natural” option (no colors), however I DO NOT recommend you this if your bird is starting to eat pellets, as
Natural pellets are bigger and too difficult to chew for Amazons.

Also, both FruitBlend and Natural taste the same.

These pellets are a little softer, but still tasty and have a good size to grab and eat. This is a good option too, I “discovered” this brand when I could not find Zupreem FruitBlend. Surprisingly, Perlita liked it.

I hope this helps your little one to enjoy eating pellets.
