Pellets and seed recomendation a work in progress
TOPS non gmo organic seeds and pellets
You can also get on Amazon
https://topsparrotfood.com/
Parrot Pellets
https://topsparrotfood.com/collections/most-popular-parrot-foods/products/tops-parrot-pellets
(They have small and large, I would do small for Cockatiels, Parakeets, Conures, Large for Greys and Amazons and Macaws)
You can get seeds and treats here too, I made the bread and most birds liked them.
