Scaly leg mites?

[SchoonerChickens]

At my new job there’s a chicken coop. They have one chicken left after the second to last died recently. I was told it was from old age; it was about five years old, as is the remaining one. I went to see the remaining chicken yesterday and her legs looked strange to me. An online search led me to suspect scaly leg mites, but I don’t know if some chicken breeds are supposed to have this kind of legs or if it’s something else. I don't know what breed this is. I also haven’t experienced scaly leg mites or any other chicken leg problems so I really don’t know anything except that the legs looked strange to me. What do you think and do you have any suggestions?

Yes those are scaly leg mites

Thank you! What is the best treatment for a bad case like this? I only assume it's a bad case by comparing pictures. I would like to help her, but I don't want to risk taking any of the mites home to my own coop.
