Im guess its a molt. My roo does this once a year, and is currently looking a lot like that in the areas where feathers are missing and just regrowing back in.
That pink patch is really a lot deeper red in color. He has no tail feathers currently and little tail and butt area are red. Im guessing it is from the sun on pretty sensitive skin.
