Okay yesterday i had 15 6 mo old white rock st. run chickens given to me. I can tell that they are mostly roo's, but there are a couple in there that have the hen face, but more roo looking tails. They have smaller heads with small combs and wattles-like a hen. They also have two longer feathers that are slightly curved at the top of their tails and small, but roo-like saddle feathers. The big roos all have large combs and wattles and prominent saddle feathers. I can't post pics
so I need some ideas on how to tell. The big roos also have small spurs starting. ( I would go by crowing-but half do that already and I can't be out there all the time to see which are doing it!)
