Here is my male about the same age as your fella notice how it has barring on the feathers.
females become a solid color as they loose all their barring
I am going to go out on the contrary limb and say female. You see how the barring is not uniform and close together? There are also feathers with no barring. I believe you do have a female that is losing the initial barring. If you put it next to a male it would be more obvious.
Color is not going to be a deciding factor. It is all about the barring. The males will continue to grow feathers that concentrate the barring in dense patterns. The hens feathers will grow out with only one or two bars initially and then be replaced by feathers with faint or no barring. You can see on Zazouse's photos above of hens, they still have some of that single barring on some feathers at that age.
And I would have commented earlier that it looked about two months old based on barring but I did not want to rock the boat too much.
