It is all a mystery to me, I am still trying to unravel it all but so many people have different ideas about this. I read that many Araucana breeders use tailed Araucana to help in their lines. There are tailed in this country. They are from breeding Araucana to Araucanas. I have one. They lay blue eggs and they are Araucanas, not EEs. What I never understood is if you breed two Ameraucanas why don't you get Ameraucanas. If I bred two purebred dogs of the same breed even if they have terrible confirmation, disqualifying faults.... they are still purebred whatevers. Why isn't it the same for chickens? A Marans without leg feathers for instance. Are you going to say it isn't a Marans?
Forgive me if this sounds like a rant. It isn't meant too. Just questioning the state of the union.
I was reading some genetics history last week..and forgive me if I get this wrong, my memory ain't what it used to be...but I think the gene for the tufts are fatal if paired? I need to go back and read that - it might have been something else, but it would explain why breeders of Araucanas keep, and breed, non-tufted birds to their birds with tufts. That would be the only way to guarantee the chicks don't have the fatal pairing.
I'll go look that up.
Edited to add - I found it. Yes, the tufted gene is lethal if homozygous dominant (both copies are dominant for the tufts). Here is a link to the article - http://www.feathersite.com/Poultry/CGA/Arau/ACARumplTufted.html
Edited (again) to add - the genetic trait for tailless is not lethal, so I'm not sure why breeders would keep tailed and tailless birds to breed to. I'm sure there's a reason, but I'm not informed enough about the breed to ponder it. :)
