Forgive me if this is a stupid question, I just noticed something about one of my chickens feet that seem different than the rest of my chickens. When her toes bend some of her toe scales pop up a bit. I can also lift them up a bit with my fingers. Here are a couple close ups of her toes. Her feet are dirty because she was walking dark colored dirt today. That isn't blood on her roosting pole.. just an FYI.. That's from a berry. There are no scabs or blood on her legs or toes. Is it normal to be able to lift up the scales? Thanks!!
