Araucana, not ameraucana. That is what I was told at purchase, and s/he does seem to have the right face shape, cheek tufts. But again, I am no expert, and when I googled trying to find out what type of araucana s/he is I couldn't find anything similar, so you could be right!
...and having just googled Russian orloff I would say you are definitely right!
Yeah she is for sure not a pure Arauacana. I could believe Ameraucana or EE but no way Araucana.
There is a big Russian Orloff thread her on BYC, put a picture up of him on there and see if they too agree.
Hope you can keep him, he is very handsome!!!!!
