Bessie & Amelia Part Faverolle?

Americauna chickens are a cross between Araucana chickens from South America and...something else.  I've been wondering what Bessie and Emelia's 'something else' was and I think it's Faverolle, a French breed.  Check it out.

This is Bessie and Amelia and their brother (long tail.)
And this is a couple of Faverelles-

Notice the feathers on their feet?  Bessie and Amelia do not have that.  The rooster is very different from their brother (yes, I hated not being able to take him home too) but look at the hen's feathering!  Pretty, huh?  Now, if these girls would just start laying we'll see how much Araucana they have in them.  This is an Araucana-


When it arrived in North America, the breeders loved the eggs, but not the rumpless look.  And so the Americauna was bred.  The Americauna/Araucana egg is the greenish/bluish one.
