I think that sometimes the painted up calves are at a disadvantage depending on where the white is on the animal, they can appear to look tight hearted or flanked when the white is just right (or wrong) in the belly, 2 calves that are identical in build and type, can look different when one is all black and one is painted.
Do not get me wrong I think some of the painted, baldies and even the Holstein colored calves look cool, just some times the color pattern can hurt them visually.
