Red dry mark on top wings

Shiro and Paul-e have this red dry rough scratch mark on top of their wings..what does this mean and how to heal them.
I think we awould need a little more detail to give any kind of answer here, ie what is the breed, exactly where are these dry marks, how long have they been present?
