I would say 90% of the time, Darker Barred Rocks are hens. There are exceptions, I have no clue if I have the only hen that does this, but logic would tell me if my Barred Rock hen can throw a Weirdo, there are others out there.

THe same bird after revealing his true identity! His name is RuPaul
This is not just a fluke, I sold 3 Pairs of Young BR's, as they matured 2 of the girls were boys........
Yours is probably a hen, but the legs do look pretty thick to me.
