One of em has a very pronounced comb for its age, but I've decided that since EEs are really just mutts, there is no reall breed specific to guage yours against, so I think you'll have to wait for the crow. Im in the same boat as you. I hatched one and bought one at the store and they are so unbelievably different its really hard to predict if one is a boy of not.
The one closest to the camera in the last pic I think is a roo, the one in the middle are it's tail feathers as nonexistent as the other one, or do they look normal size compared to the other chicks? (if no or little tail feathers on the middle one I vote roo on that one too) That is just an observation from my batch of babies, don't know if there is any validity to it.
