It depends on the age. Age at this point is where you can see the feathers. Also the color of the barred breeds.@ronott1 It seems you are always sexing based on the feathers, what are different about them from a hens?(other than the tail)
Like this, you can see pointy feathers at the neck--hackle feathers. and the pointy feathers at the back, saddle feathers. Notice that the hen in the picture does not have them and she is darker because she only has one set of barring genes.
