That was an interesting read. I'm sure many of us were playing along at home. Those pullets appear to have a nice iridescence. I love the glossy look of the Langshan. To me that's one of things that separates them from just another black chicken.
I love the green sheen too. Only other fowl I've seen with as much as the Langshans have are the Sumatra and of course Cayuga and East Indie Ducks.
