Better health for your Cockatiels. Proper nutrition is critical to the good health and long life of your cockatiel, lovebird and conure. Nutri-Berries were formulated by Dr. T. J. Lafeber and an avian nutritionist for that very reason. They contain only nutritious natural ingredients-hulled canary seed, red millet and oat groats blended with savory peanuts-rolled into berry-shaped pieces and coated with vitamins , minerals, carbohydrates and protein. The round shape is your assurance that Nutri-Berries will supply the dietary needs of your bird. Designed to change your bird's bad eating habits (pick out some seeds, ignore the others). They provide lots of beak exercise, and are veterinary recommended.
