I just bought chickens from someone who I noticed had some muscovy crosses. She said that the guy she bought them from told her they were 14 months old and purebred muscovies. My question is don't muscovies always have that skin on their face if they are purbred? Sorry I can't remember what you call it. Hers were supposed to be pure white but I also notice that they had a few black and gray feathers on their heads.
