well done on rescuing the Amazon

seems like he isnt on the best diet possible at all

the Animal zone pellets are good and most seem to take to them quite quickly

depends how you wanna go with the convertion
some do it quickly, some not so much
but if you want to try takin seed off completly and putting only the pellet in and nothing else and see how they go over a couple days i doubt any bird will starve itself
just keep your eye on their weight (weigh at day one so you can compare)
keep us posted
