I got some Americana chick's from someone who ordered them online from thefancychick.com. They are straight run a mix of blues and blacks. One is a beautiful Grey blue, 2 others are a darker blue and the rest are black. I figured since they were from a breeder not a hatchery they would be good quality for breeding or using in 4h. I am new to chickens, this is my first summer with them. It appears to me some of them look like they have a single comb. Some I guess don't look like mutch I guess they are pea combs which is what I thought Americans were supposed to have. I think they are at least 5 weeks old. Is it a true Americana if it has a single comb, do pea combs sometimes look like single combs. If it is a single comb can it be used for 4h. If you need pics let me know. I will have to go outside to catch them
