Smokey, our African grey, pulled out all his chest feathers. One day he fell onto our ceramic tile floor and broke the tip off from his beak. His “Dad” rushed him to the vets. Later the vet recommended Lafebers Avi-Cakes, because he thought that Smokey’s diet was lacking. I put him on it right away. Since then, all his feathers have grown back, he talks all the time. We also give him and our other four birds Nutri-Berries as a treat. We don’t tell them that they are good for them.
