The feathers are more likely part of Raven's mask and not actually attached to her head. The back of her hair drops down as she takes off her mask, as if she was taking off a helmet in which her hair was tucked in. And after she takes off the mask, her hair is shown to be in a more free flowing style, like Yang's, rather than the porcupine look it had with the mask on.
