Will I be able to tell if I have any purebreeds out of this hatching?
Some of the hybrids will be obvious when they grow up. I don't know whether any of the hybrids will look enough like the purebreds to be confusing.
Amberlinks are already a hybrid, so there's no way to get a purebred Amberlink.
Pure Buff Orpingtons: feather color buff, comb single, and leg color white. If any of those are wrong, the bird is not a purebred Buff Orpington. If those are all right, it may be a purebred but that is not certain.
Pure Silver Laced Wyandottes: feather color clean silver & black, pattern laced, comb rose, and leg color yellow. If any of those are wrong, the bird is not a purebred Silver Laced Wyandotte. If they are all right, it may be purebred but that's not certain.
It is sometimes possible for two purebred Wyandottes to produce a single-combed chick, but because Wyandottes are not supposed to have single combs, I would count those chicks in the not-purebred group even if both parents were actually Wyandottes.
