What gender might these Easter Eggers be?

From left to right: Cockerel; pullet; probably pullet

Are they determined by their combs or feather colors?

 

[Tricoglossus]

Both. The one with the dark red patches and red comb is clearly a cockerel; the paler "yellow" one is typically a female colour and has a pale comb; the whiter one has a pale comb so it looks like a pullet, but I am not sure about that colouration - watch for dark red patches coming through on the shoulders as that's a male colour.
