Can you get a full body pic? I think I see saddle feathers. As for breed, I'm not thinking barred rock. It looks like it has the body shape of an OEGB, but full body pic will help determine that.
Here are some full body photos... I have to say that I was suspecting a cockerel with the colouring and hackle feathers, although I just thought I'd double check before he goes to the RSPCA (I don't think my current roo would be too chuffed with another boy in the flock).
ETA: I'm pretty sure that he's a Cuckoo Marans, since it's a very popular breed in my area.
