I agree with the poster above. It appears that your EE is showing signs that of a pullet. Aside from the legs, structure, feathering (which she/he may be too young for), time is likely to tell. Within a month or so, report back to us and it may be easier for identification. In the meantime, keep watch for signs of behavior and crowing.
Trying to 'stand up' to an older hen may be something a cockerel will do. Slightly timid when approached by a bird of the same age, can be opposite.
One month is pretty young to tell, but best of luck! Beautiful birds.
