With black and white stripes in the wing feathers, clean yellow legs, single comb, and the dot on it's head, it looks like a Barred Plymouth Rock. But I am a little confused by how orange the little dot on it's head is. Perhaps that's just the color the camera makes it look? The other breed this could be is a Clean Legged Cuckoo Marans... though it wouldn't be as common as the Barred Rock. :)
