Thanks Jeremy,your first hand experience is a big help.I remember reading that Harry Lamon had pile markings and salmon breasts showing up for years.The use of good White Dorkings makes sence instead of Silver Dorkings. I recall Yellow house farm working with White Dorkings for good meat carcas,vigor,etc,and sandhill has single and rose comb White Dorkings from same pen matings.The rose comb is easy to breed out.The Dorking lays an almost white egg or slightly tinted/or very light brown.
