Black chicken

[Lolspin]

I have a black chicken that I caught in the wild. Her feathers have a green/violet iridescent hue. When she was a chick, she had a pair of white feathers on each of her wings which have since turned black.

I'd guess an Old English Game Fowl cross with either an Ayam Cemani or a Black Maran.
