I only hatched Bourbon Reds so I don't know if this will help anyone. Here are a couple of the last pics I took before they went (last Saturday) to live on a farm where they could have more room.
The tom is a bit darker and larger than the hen. He would display but was just learning to gobble when he left. The hen would "puff up" when she was trying to show dominance to the roosters and hens but never displayed like the tom. Mine "barked" as a "warning" or "I don't like that" (picking them up) and would make a "thut" or whistle when they were out ranging to keep track of each other (I miss this....). The hen has a row of feathers down the back of her head/neck that the tom does not. The tom's head changes colors often and his snood would get longer or shorter when it changed, the hen had very little change.
My tom was darker and had a black edge on his feathers that the hen did not have...lower right shows it best.....

Best pic showing color difference.....it is subtle but it is there.....

The hen is in the foreground and you can see the ridge of feathers on her head/neck...
also not the tail feathers on the tom have a distinct band while the hen does not.
