Hi everyone! Azalea, the Easter Egger chick in question, is in fact, a pullet! She and her sisters are about 14 weeks old. She has no male feathers. Her comb and wattles, while still ever so slightly more defined than the other Easter Egger's, are female. We do have one unexpected male (a buff Orpington) from the bunch and he has been obviously male for a couple months.
Thanks everyone for your input and guesses! She is a girl! Yay!!!
