Easter egger roo?

[Steamboatchicks]

So I have 7 chicks all look almost identical except one. So I'm not sure if it's the different breed that is making it look more like a roo compared to the others or is just normal they are just over 4 weeks now

It's too early to be sure, but I agree it's suspicious - comb, feather pattern, and stance are all showing early indicators of a cockerel. Try posting updated photos in the "What Breed or Gender is This?" forum when the bird is 10-14 weeks of age.
