I would be tempted to use some ivermectin pour on or Ivomec 0.1 ml per every 2 pounds of weight on the back on her neck along the spine, just in case she could have scaly face mites or other mite that is not easy to see. Make sure the product is 5 mg per ml, and the cattle medicine is fine to use on chickens. Repeat in 14 days. Toss her eggs for 14 days after treatment. Vaseline can also be applied to the face scabs to smother mites. What do you feed her?
