Hen with lifted scales

[Ry123]

Hi everyone I have had a hen who has had a lifted scale for about 2 years now so I never thought anything about it. I would give her a spray that was suppose to be for lifted scales but it never did anything. However today I found out she has gained more lifted scales. What can I do? She eats well she moves around fine and doesn't seem to be in any pain. Any help is appreciated.

Might she have scaley leg mites?

Maybe. If she does what do I apply on her feet?
