Stevie Nicks + mystery chicken

My husband named this chicken Stevie Nicks when she was just a baby because her coloring and unruly feathers gave us that 1980’s Stevie Nicks hair vibe. Since then, her coloring has become more defined, and her feathers have smoothed out a bit. I also realized I have no idea what kind of chicken she is. We only have one like her, and I don’t remember ordering her earlier this year with the others. I always order at least three of a kind, so I am completely perplexed on what she is! Personally, I think she looks like a hawk, and for all I know, she is. Any ideas?
