The comb and wattles look very feminine. The tail feathers are nice and straight too. A cockerel's tail feathers are more curved. On the other hand, there is some uneven coloration. That can signify that it's a cockerel or it could be a female with some incomplete lacing. The other thing that's slightly concerning is the pointy looking feathers on the back/ saddle area. I'm not entirely sure what I'm looking at there. I can't tell from these photos whether they are juvenile feathers with a narrow area of white that makes the feather shape look more pointed than it actually is or if they are male saddle feathers coming in. Overall, I am pretty confident that you have a pullet. It would surprise me to see saddle feathers coming in on a male with that little comb and wattle growth. If you can get a closer photo with more detail of the feathers on the back between the wings, I can tell you with certainty.
