Yes, it can, they can recover from some pretty terrible looking wounds as long as they don't get infected. It will take some time, weeks to months. Trim back any feathers getting in the wound to help keep it clean, use small scissors. Preventing infection is most important now.
I would apply plain neosporin or plain triple antibiotic ointment to the wound a couple of times a day, as needed, to keep it covered in ointment and moist, that will aid healing. As long as there is no infection, there is every chance that it will heal and she will recover fully.
Monitor for any bad odor or discharge, those would be signs of infection.
This thread has some pictures of some pretty large wounds during healing, to give you some idea of how things will look.
