Are we sure about the age? At 8-9 weeks this would probably be a cockerel too but the comb size and color is the only thing making me think that.

This is my easter egger pullet at 10 weeks, you can see how much smaller and paler her comb is compared to your birds.
As to breed, both of the birds pictured have some feathers on their shanks so I would suspect olive eggers (with a dark brown egg gene from marans)vs "regular" easter Eggers.
Easter egger is a catch all term for a mixed breed that has a potential to carry a blue egg gene (hens may lay blue or green eggs). There are many ways to make them, but ameraucana/americauna mixes are one of the most common. They often inherit beards/muffs from the ameraucana genes which reduces the size of the wattles so it often appears they don't have any.
