At this point, I agree with all the pullet guesses. My EE's are sometimes very hard to tell, they tend to be slow maturing compared to some of my others. Coloring looks pullet, nothing screams cockerel. I would think in another 5 -7 weeks you should have a better idea. Sometimes waiting is the best thing to do with them. I've been fooled by pullets I thought were cockerels and vice versa.
