The mother of this 2 month old cockerel is Cream Legbar, which has kind of off-white legs and a single comb. I am trying to figure out who the father is, Silver Laced Wyandotte (yellow legs and rose comb) or Sumatra (slate legs and pea comb). At the first sight, when he hatched and I saw yellow legs, I thought, it was SLW. When he's got older, I started having doubts. His tail is really long as Sumatra's and his comb looks like pea comb as Sumatra's, only twisted (why is it twisted, by the way? CLB has a comb curved to the side. Is it a defect or a trait?) I would appreciate if you could, also, elaborate about genetics. Thank you!
