One of my EE cockerels (on right in first pic) I had a while ago. You can see how splotchy he was and different looking even as a baby. These are between 8-16 weeks and not in order but yeah. Yours is a pullet.
It has no pointy hackles and zero saddle feathers which it would by now. Plus no comb development which it would also have. As well as a female specific and even color pattern as opposed to splotchy red all over.
