Dominecker is a general term that was used in "olden times" to describe birds with the barred pattern.
Dominiques have a rose-comb, less definition in their barring and are generally smaller. They lay brown eggs.
Barred Rocks have a single comb, are "blocky" and have straight lines going over their bodies on each individual feather. HOWEVER, hatchery stock can have similar lines to a cuckoo maran and dominiques. In this case, the comb is sometimes the only way to tell the difference between the two breeds (Dominique and Barred Rock).
, as I find they have perky personalities and are good layers. I like the fact that they are a heritage breed also. Sweet, fat hens that lay pretty brown eggs...can it get any better? Well, except my big, blue roo, of course!
