These chicks are too young to tell gender yet. Where did you get them? Were they sold to you as sexed pullets or straight run? Male specific traits (especially saddle and hackle feathers) won't start showing until about 10-12 weeks. Easter Eggers are a mix of any breed with one blue egg gene parent and their coloring is always a surprise. A pea comb and puffy cheeks/beard will mean one parent is probably an Ameraucana or Araucana. A single comb and yellow legs likely has Cream Legbar parentage, but yours look to be the former. If you call the hatchery or farm where you got them, they might know the breeding stock that was used for your batch, but even knowing the exact parentage doesn't guarantee any particular feather coloring and even egg colors can end up green, cream, pink or pale brown.
