So how can I tell the difference between a Barred Rock rooster and a Cuckoo Maran rooster. I thought I was getting a Barred Rock rooster and then I just saw a picture of a Cuckoo Maran rooster who has a white feather in his tail feathers and so does my rooster. I'm confused. Help please. Sorry I don't have a picture of my guy. I was going to start breeding him to my Barred Rock hens for purebred chicks, but now I can't for fear my customers won't get what they ordered.
