The irony is, if it's a boy? He has the genetic make-up to be the biggest of them all. The father is an Aracauna rooster, so he has those genes. Because I only have one breed with feathers on their leg, and the little guy has them. I think it's safe to say the Brahma is the mahma. The Brahma breed is a large breed. If he has the male Brahma gene, he's probably going to be kicking Dad's ass in about 8-9 months. If he is a she? Well?????? I won't say on a public forum what is likely to happen.
