UPDATE:....it's now 1 month later, and yep, the two chicks with the thinner/sparse tail feathers are roosters. They even try to crow. Their tail feathers were very distinct and different within the first week, but by week 2 they all began to look the same. So there must be a small window of tail feather growth pattern that can distinguish the sex. Perhaps this is known for the breed of BCM?? Don't know, this is my first hatch. But I just thought I'd report back. Happy hatching!
