I would have guessed hens on the original post, the last update shot still hasn't convinced me otherwise. Here's my roo at 6w:
Girl, left. Boy, right. About 4w. You can see the girls legs, the banding, the obvious thick white on the boy.
Boy, left. Girl, right at about 8-9 weeks
My male at 9 weeks:
And then at about 20 weeks...
Hope this helps some. :) Enjoy them! I'm loving my barred rocks, both of my females and my roo! One of my girls just started laying and her eggs are bigger then my RIR eggs, and she's been laying for 2 weeks haha. My girls are very similiar in band color, but I can tell them apart because their faces are different. One has a more scrunched up and less red comb while my 2nd girl has a more straight if a bit flopped over and deeper red comb. :) It's better having a bit of differences, easier to tell them apart!
