What you are feeding is perfect! The best diet for a Grey is nutritionally balanced and varied, with different tastes and textures. Greys can get very bored with a pelleted diet, which is why including Nutri-Berries is the perfect choice since they are nutritionally balanced the same as a pellet, but they are not ground up so they provide natural foraging exercise. And they are perfect for foraging activities since they can be hidden in toys and other things for your Grey to find and eat. Lisa Bono will be presenting nutrition for African Greys as part of The Grey Way series, so keep an eye out for that possibly in May.
