Boy did this freak me out! My husband calls me outside to ask if I am missing any chickens with black wings. As I am walking to him I am counting chickens... 3 speckled sussex, 6 red stars, 2 black orps, 4 cream legbars, 1 black star....etc etc By the time I got him him I said "nope, no missing chickens" and he says, weird, because just over the fence there is dead chicken parts. I went with him and took a look and confirmed it was not our chicken. We are all on large acreage in my area, this bird would have had to come from 1/2 mile away!! Whatever took this chicken traveled a good distance before eating it. I guess, it's time to drive around and find out who lost a chicken.... All the predator left behind was one wing and some feathers.
