Instead of grinding down the ingredients into a pelleted form, the ingredients in El Paso Nutri-Berries are left mostly whole to give your bird zesty flavors and textures pelleted diets lack. And, unlike vitamin- and mineral-fortified seed mixes that lose their health benefits once the bird cracks open the seed, Nutri-Berries are made with hulled seeds and grains. Each berrie is then coated with essential vitamins and minerals to ensure that your bird receives balanced nutrition in each bite.
