It is hard to see in these photos, but they all look like toms to me. When I'm trying to figure out what sex they are, my first clue is the "shooting red", when the toms get a bright red color down the front where their caruncles will develop, Then I look at the snood, which is thicker on the toms. When they are older, the toms lose the feathers on the top of their heads while the hens retain a "mohawk" strip of feathers down the middle of their head. The tom's heads will generally be a bit wider, too, more masculine-looking, and thicker legs. These are all the characteristics I use and when put all together, can get a good idea.
