I really want to get into breeding chickens and I an so theoughly confused when it comes to dominate traits and what chickens create sex links. I have a few heritage breeds and also have a few ayum cemani. I would like to keep some just heritage breeds but I love playing too and would like to know what I am doing. I had a speckeels Sussex roo in with my patridge rock, barred Rock and a few others. The partridge chicks look very much like patridge rock and the barred rock like the mothers as well but they wont creed true with a roo of there breed, correct? Are there books or websites anyone suggest? I looked at the site that you enter hen and roo and was just so very confused. Any help is appreciated.
