> dunmovin farms My heifer must be heterozygous polled and carry the scur gene because, she has horny tissue under the skin (has not come through yet)it is not atached to her skull. Her older half brother (same father) has the same thing going on but his scurs have come through the skin they are only a half inch long. Do you think they are polled and scurred?
