I would say the rooster tail should be getting longer by now. Also aren't easter eggers a mix of americana and araucana? If so maybe you have a hen that won't get much tail, hopefully. What does her comb look like
The silver one has a very small, pale comb. The orange one is much larger than the others and has a large, orange comb. You can enlarge my pics by clicking on them to get a better view.
These birds are so different. From my red sex links I raised last year. They look nothing alike and are so skiddish!
