with angel wing, the wing begins to stand out like a hitchhiker's thumb. If you wait till flight feathers are grown in it usually is too late. If the wing is hanging down and she brings it up to correct it then that is usually the blood as the feathers are growing making the wing heavy and as she keeps adjusting the wing to normal position then the wing will finally be strong enough to hold in a normal position. Can you post pictures of what you are talking about?
