Also adding in, depending upon what she is doing, she *could* she the EE. In showmanship, breed doesn't really matter as they aren't judging the breed to the standard. If she wants to enter the bird in the exhibition portion, she will, of course, not be able to show the EE. My friend's daughter uses a Modern Game in showmanship but enters him, along with 2 silkies in the exhibition portion.
x2 some judges are picky about non-standard breeds in showmanship- I learned, and some just let you use them. I've seen many people use EE's, but you have to hold the chicken for quite a while! There are some bantam silver laced Wyandottes, depending sometimes where you live, their rare to get from a breeder.
