Ack, you hit on my pet peeve! But, I detest the term "Dominecker". First, it's Dominique, second, if it has a single comb, it's not one. I had a huge discussion in a feed store once. The label actually said "Domineckers". It was a brooder full of Barred Rocks. I told the lady that I bred BRs, I know one when I see one, not to mention that "dominecker" is not a breed at all. She said the FFA guy did not mention it, as if that meant anything. I bought my first rooster from an FFA kid. He was fed only corn, had lice and favus and was in a dark, dank pen in the woods with a huge turkey who was beating him up regularly. I grabbed the big color breed book to show her the difference, but she wasn't having it. Said, maybe the comb changed later. ARGH! Don't you love willing ignorance, another of my pet peeves, LOL.
Folks used to come here and say, Oh, is that a Dominecker? Noooo, it is a Barred Plymouth Rock, a different breed entirely. They looked at me in total confusion.
