This innovative new product contains Nucleotides which can improve your bird's immune system. Manufactured with 15% Protein and 8% fat in a small morsel. In a natural color with no artificial colors. Sized for African greys, amazons, small to medium cockatoos, larger conures, small macaws and similar sized birds. Our Natural Gold bird food is so named because we do not use any artificial color enhancements to achieve the rich natural gold color of the food. The word natural does not apply to the other aspects of the food. Natural Gold does contain vitamins, many of which can only be produced synthetically.
