there aren't any barred ameraucana although someone said they are/are going to be trying to, sorry can't remember who......
Gary (geareduplyn) has some project araucana that are really nice looking, can't remember what the pattern was called but they are similar to this araucana
and I haven't seen anyone that breeds barred ee's here, hopefully someone will let you know if they do.
I have some Barred EE Sex links, only mine are still eggs, LOL
I have a EE Roo over two Barred Rock hens, (plus the EE hens and a couple RIR hens too.) From what I read, they should lay a Olive colored egg, I suppose eventually you could get a Barred EE who lays blue eggs?
I can't tell which eggs are the RIR and which are from the Barred Rocks though! My breeding pen is not escape proof, it seems!
The barring is a dominate sex link gene in the Barred Rocks, and Dominiques It surpresses dark pigment thats why the leggs and feet in the above are not dark. The Hens have two of these while the Roos have one. The Hens are darker.
