Is this a rooster?

[saraem18]

I got 2 Easter eggers a few months back and was told they're hens. One turned out to be a rooster, they looked the same except he started crowing and his tail feathers started getting long and curling.
We lost him to a raccoon attack 2 weeks ago, and since then this one started crowing and being aggressive to the other hens. S/he is the same age as the other but the tail feathers aren't long like the roosters were and the comb is smaller.
Is she a rooster or is this normal behavior after the loss of a rooster?

Definite rooster. A beautiful one too.

Look at the saddlebag feathers... tell-tale sign of a roo.

That's a rooster, a very handsome one for sure!

Cockerel.
You didn't hear from him before because the one you lost in the attack was dominant and most submissive males will not crow when the dominant is around.

That's a rooster. @DobieLover has explained the reason for his not crowing.
