Hello, So I noticed that one of my BRs looked liked this (see below) and it seems to cover a large area. I do not see any "dirt" just dry and scabby skin. I haven't notice her being pecked...as a matter of fact, she's queen b....the run is sand with DE. They do free range. Should I treat for mites? She just came into laying last week so I don't believe she is molting. Thought?
