I recently acquired an Araucana breeding pair, however, the female is only about 3 months old so no eggs from her yet hehe. I am aware of the lethal tuft gene, as the rooster is tufted and the female is not. I have 3 red star hens that lay exceptionally and I'm curious to know, as I penned one of my red star hens with the Araucana roo, will the rumpless and tufted genes pass on to the chicks? The reason why I'm gonna try and breed the two is because I want some olive eggers for my flock at home (Yes, I know olive eggers usually come from breeding Marans with Ameraucanas). I know that because Red Stars are a hybrid/sex-link chicken, that the chicks will not come out to be sex linked, but what I really want to know is if I'm going to have to worry about chicks dying inside of their shells and etc. since that is what happens when breeding araucanas. All of my chickens come from private breeders, and yes I am sure my Araucana's are not Easter Eggers or Ameraucanas.
