A family were left stunned after one of their sheep gave birth to rare twin lambs which were born completely different colours - one black and one white. <br /><br />Tracey Simpson went to bed on Saturday night (15/3) knowing one of her ewes was due to give birth any minute at their farm in Wem, Shrops.<br /><br />But she was unprepared to find the two lambs in the field the next morning – one black male and a white female.
