Classic Nutri-Berries are nutritionally balanced like pellets, just not ground up. Like pellets, Nutri-Berries contain seeds and grains. In pellets, however, they are ground into a fine powder and then formed into a pellet. Most of the seeds and grains in Nutri-Berries are kept whole because Dr. Lafeber discovered how to nutritionally balance them without grinding. We naturally preserve our foods and like all our foods, Parakeet Nutri-Berries are free of artificial colors, so you can feel good about offering them to your bird, either as a complete meal or as a healthy treat.
