She has Scaly Leg Mites, so she may also have Scaly Face Mites.
IF at all possible, I would try to get some Ivermectin Pour On and treat her. You still want to apply an oil or ointment to the legs and face. I would also try an oil/ointment on at least one of the scabby places on the body too. Vaseline (Petroleum Jelly), Castor Oil or similar can be worked into and UNDER the scales of the feet (SLM live under the scales), I like Vaseline for the face.
The skin problems on the body may not be due to mites. Marek's, some type of fungal or bacterial skin condition, etc. may be the issue there.
