Does anybody know what breed this is?

Hi all! This morning, a chicken wandered into our coop (we also have no idea where she came from, we are the only ones with chickens for a couple miles or so) and I was wondering if anyone could help me identify her? I have been struggling a bit. I will include a picture as well, but she has a fluffy black head, a yellow body with black spots, little "devil horns" instead of a comb, and a fairly long tail. She is also pretty small compared to our other chickens, and can squeeze through our fence. The first picture is horrible quality, I know, but it is currently the only picture I have that shows her full pattern. She is very, very skittish and fast and it is really hard to get a good picture. The second picture shows her comb and head.

It looks like she is definitely missing some of her head feathers, as they are quite scruffy and patchy, which is either from our chickens pecking at her or from whatever journey she's been on.

I'd guess mixed breed and part Crevecoeurs

I think probably an appelenzer spitzhauben mix. Her comb looks intermediate between a couple of different comb types to me. It is massive!
