when seeing easter Eggers (or any pea comb really) if it's red around 6-8 weeks and bulging, you have a cockerel. That's really the only way you can tell with solid easter Eggers at this age. You won't see sickle or saddle feathers for a long time.I agree with those who say this looks female but the comb is throwing us off.. If asked to choose one, would say female.
There is too much of an obsession with looking at combs only for sexing. Need to look at rest of the bird also. You can start parting the feathers on back, saddle and neck area for pin feathers and look at the shape of the new feathers emerging from them. Rounded tips, same flat color as what the bir currently has- female. Sharp pointy tips, much shinier and also with 'fringe' look to the edges away from the tips-male.
If they are patterened, red, white or black splotches on the chest indicate cockerel. Red splotches on the wings are cockerels.
Even patterning (not splotchy) or salmon on the beast indicate a pullet.
