Classic Nutri-Berries are nutritionally balanced like pellets, just not ground up. Both pellets and Nutri-Berries contain seeds and grains. In pellets, they are finely ground before being 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 them down, leaving the taste and textures in a more natural form that birds find appealing. Lafeber is also a balance off the Omega 3 & 6 fatty acids to boost your birds immune system and to promote healthy skin and feathers. Lafeber’s foods are naturally preserved and free of artificial colors, so you can feel good about offering them to your cockatiel or other small- to medium-sized bird. 10 oz. Bag
