I agree with
@WallacetheKhakiCampbell that she has Scaly Leg Mites and needs a nail trimming.
Slather some vaseline, castor oil or Nu Stock cream onto her legs and toes, working the oil or cream up and underneath the scales. This will help smother the mites. I would apply the oil/cream at least once a week for a month, then re-evaluate. Treating SLM can be a process. An alternative treatment is to use Ivermectin, but you will still want to apply some oil to the legs to help them heal.
Nail trimming, you can trim a bit each week to get them shaped up.
