I've always assumed that the Dominique hen I have, Duck, is a Dominique because her coloring is the same as her buddies. I'm wondering about this though because her comb is different than the other dominiques. Duck has a single comb and the others have rose combs. This is a picture of two of the Dominiques. The blurryish one in front is Duck. In the back is one of the other Dominiques for comparison. Here's a better picture of Duck: Any ideas?
