Hen or Roo?

[Tigercub522]

These are two of my 6 week old chicks. I suspect this one may be a Roo but just looking for opinions. The first 2 pictures are of the one I am questioning, the last picture is one of the others we got at the same time, we were told both are Olive Eggers and are just sweet as can be and love being held.

Still young but I'm also thinking 1st one is a cockerel

Small bits of bright red on the plumage scattered screams male to me.
