Dominique--maybe (I can't tell if it is, but it doesn't look obviously wrong to me.)
Cinnamon Queens--no. One reason is that Cinnamon Queen hens have white and brown feathers, not black and brown. (Google image search is my source of info for this.) The other reason is that I'm pretty sure the one on the left (next to the white bird) is a male, while the one beside him is a female. If they were Cinnamon Queens, or any similar sexlink, the male would be white. You might have Rhode Island Reds, or New Hampshires, or Production Reds, or something of the sort; or you might have something else entirely.
Black Sexlink--maybe. I think it has quite a lot of gold on it, but I know that some Black Sexlinks do have quite a lot of gold, so I don't know for sure. IF it is a black sexlink, then it is a female.
Where did you get them? Yes, the labels can certainly be wrong!
