There are differences between yours and mine but yours are the closest i got . The black feathers on yours are a turqoise on mine, but the faces and the bodie slook the same, might actually be more dark brown. I was told mine were americaunas. (ee) their feet are yellow, the boys' tails are...
do you know what breed they are? That might help a little... they look like a few i have and i know what i was told they are, curious to see what breed yours are.
