Can anyone explain how to tell the difference between a Barred Rock and a Cuckoo Maran chick? My chicks are about 5 weeks old now. I ordered a Barred Rock Pullet and a Dominique Pullet, and a "Meal Maker" from Meyer Hatchery, as well as other breeds. The Dominique is smaller and has the rose comb, but I have 2 that look almost identical with a single comb and I think that one is the Barred Rock and one might either be a Cuckoo Maran (as my "Meal Maker") or another Barred Rock. How can I tell? Do I have to wait for them to mature to tell the difference? One is extremely calm, quiet, and friendly and loves to sit on my hand or arm.
