Link: Look at his Japanese site!
I like this shot above very much as it illustrates the position of the hens' tails - wide open and well-spread. She was showing her tail exceptionally well-fanned open because she was calling her chicks at the moment this shot was taken. "At rest" their tails are still carried open and rounded, but as fanned open.
A nice shot of high-quality Shirozasa showing young cockerels already with a beautifully-spread tail!
