Sorry I did not see your last post until I had posted. Good to know you got a couple of females. Barred Rocks and Dominiques are almost interchangable.

Barred Rocks and Dominiques are almost interchangable.

"Interchangable"?
If you mean they're both dual-purpose breeds, good layers of brown eggs, then yes.

If you mean they look alike, then check combs: Dominiques have rose combs, Barred Rocks have single combs. (Which is why OP's rose-comb chickens are definitely Dominiques, not Barred Rocks.)
