Pellets are a formulated diet for our parrots, much like the kibbles our dogs and cats are given, but specific to the needs of parrots. They contain grains, seeds, vegetables, fruits and proteins with added vitamins and minerals. The ingredients are mixed, and then baked. Some are made into shapes, dyes and sugar added. Some of them contain only organic ingredients and human grade grains. None of them are complete. We can send a man to the moon, but we can’t duplicate a parrot’s natural diet.
