Didn't see the potential parentage section....oops.What makes you say it's a cockerel? It have zero comb or wattle development. It sound as if they very well could be cross-bred, meaning the barring has nothing to do with it. Anyway, you can't really rely on barring with hatchery birds, as the genes get all muddied up.

Where hatcheries are concerned, though, I don't believe they're as inconsistent as people make them out to be. While not normally perfect, main breed characteristics still remain on most hatchery birds.....making them easily identifiable. The large majority of my own hatchery stock's stunning and, overall, decently correct. (quality also depends on the business.....Cackle, for example, is fabulous) Leaving margin for exceptions, there are still general patterns that can usually be followed.
