Exchequer leghorns are Extended Black as the Fenotype requieres Extended BlackYou're not from the states are you?
I understand that but it has nothing to do with what I was saying.
Our SOP did and as far as I know still allows dark wash on shanks for the black variety.
My point was that blacks are hard to find period. Some I've heard about also breed in Minorca etc just to improve them and increase gene pool.
White Leghorns are everywhere. If they were carrying extended black genes it seems we'd have more blacks around and a larger gene pool.
It would be easy to breed out the dominate white genes.
