By the way, my experience has been that the cockbird is very important as concerns the comb of the offspring. Most of the birds descended from our original UK import produced roosters with too large a comb, twist and thumb mark, and the comb going too far out on the beak. Lowell and I also acquired a pair of cockerels from a breeder in Oregon (who does not want to be identified), also of British origin. They had superior combs and super colors (including eyes), and the pullets resulting from them also laid a large, dark egg. I lost that line to predators, but Lowell still had some of them at the time of his passing. The wrong eye color was a challenge from the very start as concerns the birds (i.e., eggs) we originally got from the UK. The ones from British Columbia (German origins) were better in regards to both combs and eye color, whereas their plumage patterns/color (especially the cocks) and type were quite at variance with what we decided to go for. I cannot recall if Erhard's birds (also of German origin) had these characteristics.
