Thats how I ended up with my white pheonixes. The people that had the originals before me just got lucky enough they happened to never have Whites hatch out, then I get them and BAM Whites everywhere.Each of those birds is essentially a coin flip whether or not they have it. So you can luck out and just happen to pick the right birds to eliminate the trait, but odds are pretty high it'll haunt you for a long time before that ever happens
