EE pullet. A cockerel of this color will show some color in the shoulders and/or neck and saddle. Also, a cockerel at this age would have saddle feathers anyway.
I have an EE roo that looks just like her except he is 4 months old. Much larger tail and hackle feathers. Larger and redder comb as well. That is a pretty pullet. Ours was banded as a pullet but turned out differently.
I have one just like her (well very similar, mine looked like yours when a bit younger but is darkening up, so yours might as well ), she is now 6 months old.
