I recently bought a pair of Japs. The seller told me they were Birchen Japs. They both have a blue-green shine to their feather and silver stripes on the neck feathers. The rooster has more than the pullet. I was wondering if all you experts could tell me what you think of them as per type and such, so I can get a better idea of what the breed is supposed to look like. Also I was wondering, are they long legged?
