Yikes! Even though I have had Sophie forever i'm not a feather expert as Sophie never chewed her feathers or showed me a molt.BUT...I have had her for 13 years,and if I saw two feathers in such a short period of time, it would make me watch her closer. How is preening going, how is flying, and how is diet and general happiness and socialization with rest of animal kingdom. Those would be my own personal questions. If I was furthur concerned, to the vet.If your not seeing excessive preening, just monitor Storms activity. And Yes.... they do molt differently. Nancy
