LORD NO! I just have the regular guineas. Dear sister picked them up, and told me they were opalines, lol. I don't really care, as I got them for tick control. I do plan on cooping them at night. We have Great Horned Owls, and that light color would be a bad thing at night in a tree.
I got these for $2 a keet, when regular pearls are going for $4+ dollars, so I'm pretty happy with them. I looked at them today. They still look white, and it's my understanding they will be white until their first moult.
