I got 14 BR packing peanuts this morning, and I'm thrilled about it. I know packing peanuts are supposed to be males, but it would be okay with me if they made a mistake or two... So I have a question about head spots. How accurate is it judging gender by size and shape of their head spots? Some of them have huge spots (like stripes across their heads), some have almost none. Is it greater than 50/50 chances that head spots tell you the gender?
