I got two little Buff Brahma when they were about a week old. They were both the same size, just one light and one dark so we could tell them apart. They are about a month old now and I've noticed some significant differences. The dark is not growing as fast. Dark has more developed wing feathers and no neck feather growth. The light has gotten huge. He stands as tall as some Buckeyes that are 2-3 weeks older. He's all legs. Big wide legs. He's the closest looking chick I've seen to a velociraptor in body. He has fuzz on his wings still, but has very defined feathers on his neck. So is it looking like the light is a cockerel and the dark is a pullet? I know it's probably too early to tell for sure. And I don't even really pay attention until I see very pronounced differences between individuals. So far, I've been right with all my other breeds, but these are my first Brahma and the first time I've seen such size/proportion difference. Anyone care to offer an opinion? Thanks!
