Scaly leg mites?

Hey all, does this look like scaly leg mites ? She’s been lethargic and unwell for the past few days.

My chickens came with the house that I now live in. They aren’t hand-tame so ive been anxious about them getting sick and not knowing how to help them. I try to take the best care of them I can and I keep their coop clean. Any advice is very much appreciated
