You can start recall with a clipped. Just start with target training. When she touches the end of a stick or your finger you click and reward. You move the distance she would have to walk to touch target and continue the click and reward. When she starts growing out wings you have her start on a perch and fly a short distance then increase the distance. Of course clicking and training through the whole process.
Want to add that you can encourage some flight depending on severity of clip. If he falls like a rock then perhaps not. But if he can get a little glide, you can condition his muscles to carry him a little bit.
