Is the wing still bleeding? The blood in the photo could just be a blood stain, but the bleeding itself could have stopped. Have you tried some flour or starch to stop the bleeding (if it is still bleeding)? If it is still bleeding and it doesn't stop you will have to go to the vet.
Clean up her feathers with some hydrogen peroxide to make sure the bleeding has stopped. If it has she'll be fine, her wing will probably be sore. If you can't get the bleeding to stop, then she will need to go to a vet to have the feather pulled.
