I see the photo example included is a roux variety. There are a few options you can have with this mix. They will be wild pattern or Italian pattern, from wilds you will have pharaoh, egyptian and falb fee among the possibilities, and Italian will offer Italians, manchurians, pearls, and autumn ambers (I apologize if I’ve missed any). All of those are feather sexable, meaning that at a few weeks of age you will see different feather patterns emerge for the different genders. But if you receive any roux males (egyptian, or autumn amber), if you pair him with a non roux (pharaoh, Italian, Tibetan etc) they will be auto sexing at hatch. The result of a roux male over a non roux female will be all roux females and non roux males.
