I just hatched 6 chicks. They are all Barred Rocks. I have read and seen the pictures suggesting the larger, more dramatic white caps and less pigmented legs and lighter/silvery coloring is indicative of Roos. I am looking at my group and I have 2 that meet all of those criteria and 2 more that have pretty substantial white/yellow caps but are not as silvery. How much should I count on this? I am aiming for 6 hens, so I will likely start another hatch now if it is pretty certain I only got 2 hens out of this one.
