When Jacob's father and Nehemiah are shearing the sheep, the sheep Jacob's father is shearing has a pinkish face and legs. When he tells Jacob that he doesn't have any money, the sheep now has a black face and legs. Then in the next scene where the sheep runs off, not only have its legs now changed back to pink whilst its face is unaltered, but its tail has been sheared even though Jacob's father never sheared that spot.
