Your second bird is gorgeous. I have an EE cockerel that looks very similar to your bird. Mine are 3 weeks old, but I already know mine is a boy because his comb is coming in straight instead of pea, and he is acting like a roo with the chest bumping and dominating. But he's already pretty, and now I have an idea of how he will feather out. I can't be sure, but chick one looks like a pullet, and your second one is a cockerel.
