Cinnamon or Golden Pearl? Wild type?
I think golden pearl males are supposed to have a light spot above their beak. And looking at your pics, I don't think your roo has that spot. But I don't know.. I also read about the lethal thing, I guess that's true. But it's only going to affect 25% of the chicks, so it's not like you absolutely can't pair two golden pearls - you'll just get a lower hatch rate or possibly a few chicks that die quickly (I believe I read most of the double factor golden pearls never hatch).
