I love it when I ask a question ... THEN ... research until I find an answer.
In the Amazon Room, I asked about Skittle's change in feather lose. Then I did a search for "Molting in Parrots" and for the link to a long article on feathering and molting aimed primarily at parrots. (Although the author, a Dr. Ron Hines DVM, PHD, admits he doesn't have much experience with cockatoos.)
I enjoyed reading it. Here's the link: All About Your Parrot's Feathers - The Causes Of Molt, Feather Problems And What You Can Do About Them
