That is a defect. They are supposed to have blue ear lobes, so she can't be shown, though I don't know about breeding her.I gave a bath to my sick silkie, the one who has skin problem, mites or whatever it is and realized she doesn't have any turquoise ear. How come? All the others have it, why doesn't she has it? h She comes from a reputable breeder, so I know she is not a hatchery or a poor quality chick.
The oatmeal bath treatment, tick shampoo, ivermectin seem to help a little bit, but she still look awful. I don't know what else I can do for her.
