Id say #3 is most likely a pullet as those saddle feathers are still rounded and not at all pointy. From what you say and what I have read tail feathers should be ignored at this age for sexing completely.
Thank you for the pictures it means a lot that took time to take them for me

I lurk on the breed / sexing forum to learn and its fun to guess. I went from no dang clue to being in-line with the other guessers almost 95% of the time. Its been fun to learn. Breeds are much much harder.
Your babies though are challenging though goodness me definitely cant just look at the comb/wattle development to tell!
