She might just be a moody girl I've had a lot of female EE's that act like that and look like your bird. I personally am inclined to believe that she is a Zoey You'll just have to wait for her to develop a little more to be able to know for absolute sure.
Nope, she's a pretty little pullet. Her kind of partridge-like coloring is typical of female EEs, plus her comb isn't nearly as developed as a cockerel's would be at this age. Some birds are just more vocal than others.
Thank you all for your input! She was supposed to be a sexed pullet, but her little barks now and then put me on edge thinking she's about to belt out a crow. Here she is with her fellow EE sisters [I hope] and a BO from the same hatch.
