I know I know I know, it's too early to sex dark brahma chicks at only five weeks. But we can't help but obsess over it everyday anyway, and watch them constantly for any new feather or behaviour quirk that we can take as a sign. I'm new to raising chicks but here's what I've noticed. Lou walks around standing up tall and curious, which Elma doesn't do. Sometimes I catch them running at each other, jumping and flapping their wings. I've heard this is typical roo behaviour. Lou is a fair bit bigger than Elma, and feathering more quickly on the chest.
