That's the hard thing about mixed breed barred birds, the males are dark in color like a purebred barred female, so it makes it hard to tell sometimes when they're younger. Your bird is male, and you could call him a black sex link if you need to call him something--he had one barred parent and one non-barred parent. That gold leakage Fred pointed out will likely increase as he gets older, and he'll get some in his hackle feathers also.
