So legs look really dark right? Head spot is pretty small and not bleeding down the neck, so it looks like your new chick could be a pullet. Only a few days old, I'm guessing?
Barred rock are supposed to be one that can be feather sexed. I hear by 3 days some places but read online best at 10-12 days. Anyway, I have seen the tail feathers coming in on some before others. This is supposed to show your females feathering faster. However, most of my experience is limited to reading- as I'm waiting to see if I'm correct with my current chicks. Good luck!
