Minorca pullet with droopy wing

I have a Minorca pullet with a droopy wing, she has been this way since she was a chick. Does anyone think cutting off the bottom feathers on this wing would be ok? Twice now she has somehow gotten it completely turned and tucked facing forward, very hard to undo this. She steps on it as she walks, I feel really bad for her. How far can you cut off the feathers on this wing? She is about 6 months old.
