Ralphie, if you go to the Greenfire Farem web site you can read all about the Leg bars. I could be wrong, as I frequently am, but I believe that Greenfire originally imported them from Great Britain.
The Greenfire site claims that the breed is a prolific layer of blue or pastel green eggs? I don't believe that the breed is accepted in the American Poultry Association as of this time, but that a proposal for acceptance has been made? Jerryse could clarify I think.
Greenfire is a poultry merchant that has imported several breeds to the U.S. in recent years. Their motivation seems to be largely financial? At one time my friend Dan Powell had an arrangement with them to market some unique color varieties of more than one breed of chicken, which Dan had developed. Dan was very knowledgeable regarding poultry and genetics and a fanatical poultryman. He had moved to New Zeeland when we last communicated.
Greenfire markets unique and seemingly beautiful poultry breeds, but I am not a promoter of them. I suspect what you get may not be exactly what they represent it to be, and their prices do not seem at all reasonable to me.
