Here is one of my LF Araucana pullets, hatched this year....far right of course. I have some dominant whites and some recessive. I'm still not certain which of my whites are, some could be both I think. I have one BBR hen and she's the one that makes my red pyles when bred to my white rooster.
You don't have to go out of the breed to make an Araucana in Pyle. If you're interested, I'll probably have some chicks in the spring. I've sold all I had but one poor quality, but loveable, cockerel. He's got an incorrect comb, a couple of tail feathers but otherwise should be better than going out of the breed to make a LF. You can have him for the cost to ship if you want him. PM me and I'll take some photo's for you of this cockerel. His red leakage is pretty pale but there. Breed him to a BBR red hen and you might get what you're wanting. (those of you here that understand the genetics better please correct me if I'm wrong)
This was actually an old thread that I found that was interesting to me.
Just inquring if this person has ever got their Leghorns going.
