easter egger - gender help!

[mngllilly]

I have 3 6week old easter eggers and I'm starting to suspect that 1 may be a cockerel. Can anyone help me confirm or deny? The chicken in question is the only one of the three with a noticeable comb (albeit light pink comb) and its tail feathers are growing more upright than the other two. Thanks!

You intuition is correct, that one is a cockerel.
