I have two 6 week old Salmon Favorelles from Mypetchicken.com. They are supposed to Salmon Favorelle pullets but one has a black chest with brown wings and some white tips on the wings. Is it DEFINITELY a roo? Or could it possibly be a dark hen? I am so nervous that it may be a roo. How is the temperament of SF Roos? I will attempt to post a photo. PICS in a subsequent post!
