I agree, your suspected roos are actually roos. As far as the claims of the breeder, I hate to break the news to you, but they were not being entirely truthful with you.
Genetically speaking, a true Barred Rock cannot produce a blue egg laying offspring in the first generation, no matter what she is crossed with. She carries the brown egg gene, which, when combined with the blue egg gene, will produce a green egg layer (it's like paints, you can't combine brown and blue and come up with pure blue. You'd have to combine white and blue. The same is true for eggs). Now, since EEs are already a question mark genetically, it's entirely possible that they too are carrying the brown egg gene. If that's the case, crossing a brown egg EE with a brown egg laying BR will produce brown egg offspring.
Most likely, you have hens that will lay green eggs, but be ready for brown, it's a possibility.
