Hello, I am new to BYC and have some questions about breeding heritage sexlinks. I have a few Light Sussex hens and I just put them in with a Buff Orpington Rooster. I'm hoping to have sexable chicks soon. I was wondering if I put Silver Sussex or Coronation Sussex hens in with a Buff Orpington Rooster will they also be sexlink chicks? Lighter males and buff females? Also will CouCou de Maline hens work as a sexlink project instead of using Barred Rock hens?
