The person who uploaded the pic in your first link hasn't been online since the beginning of March. Maybe they don't get online too often, so you might have to wait a while for a reply.I didn't either until I saw a pic of them on this site : https://www.backyardchickens.com/gallery/6696750/
but the lady doesn't reply to me so ??? I've tried complimenting her birds and including her in conversations...nothin yet.
Anyway,... I've also found them here: @ http://www.sandhillpreservation.com/catalog/chickens.html
However ordering from these guys is something of an endeavour, plus I'm not tryin to buy 25 new babies and breeds I'm not interested in just to have to turn around and sell them off OR once I find out after brooding them in 6 weeks that the bird I fell in love with is a Roo. OH well, that's how it goes I guess.
But yeah, they are a great lookin bird and I can't wait to own several!
