Hi. I have 5 buff orpingtons. One of my hens has like dark ear feathers and none of the others do. It has been like this for awhile and someone told me they are just dark feathers. But I find it strange none of my others look like this. I might be crazy but wanted other opinions on it. Its both ears and she acts completely fine. I check her ears and skin and there is nothing in it or on her. It has gotten darker over time. Like I said, I could just be crazy to worry but wanted to see what others think since I've never seen another buff orpington that looked like this.
