If you ask me the buck in the first two pics and the one in the third are different deer. Pretty obvious to me. The top buck is a lot bigger, knocking on 180 I would say. Buck in bottom pic looks like a mid 160's. Top buck has shorter brows spaced more widely apart, with a dagger point coming off his right base, bottom buck has much taller, closer together brow tines, is narrower, lacks dagger point and has an overall smaller rack. Looks like the same genetics, but different deer, not a bad problem to have at all.
