I was given a 4 month old rooster, Sam. The lady said that he is a barred rock. I have seen several pictures of this breed, but I haven't seen a picture of one that looks like Sam. He looks like a barred rock but he has brown and gold feathers mixed in with his black and white feathers. He also has green feathers in his tail. Tonight, I saw a picture of a sex-link that looked almost like Sam. I am new to having chickens so I need some help in determining the breed. This is a picture of Sam, but it doesn't really show his colors. I will try to get a better picture if it will help. What breed do you think he is?
