I recently got an adult RIR hen and she almost immediately started going through a molt. Now two months later she has her feathers back but I see that she now has a few solid white feathers up near her hackle feathers on her back. She didn't have any white feathers before. Can a chicken change colors like that? Could she be a mix breed instead of just RIR? She originally came from the local feed store as a hatcheray chick.
I'm going to have to go out and take more pics of her to see if she changes like that through the years. I'm believing that she is about 3 years old right now.
