The problem is this. There is no "Breed police". Thus, in the US, the hatcheries crank out all kinds of birds, almost none of which are true bred to the Standard. They can and do call them anything they wish. Just about anything red gets called RIR, New Hamp, production red, etc. They sell all kinds of BLS, commercial blacks, tons of different Red Sex Links, most with some kind of "cute" name. They sell made up, invented versions of Easter Eggers too, passing them off as Americana (sic) and other invented names. It just is what it is.
We've got more Tints and Ambers and Reds than you can shake a stick at.
True bred, bred to the Standard birds here are really only going to be sourced from breeders. The rest is profits, marketing and salesmanship. The hatcheries serve a purpose. Available, healthy, cheap birds. That's what they do well. True bred birds? Not so much.
