Sex link chicks

[chic101]

My 6 chicks are three weeks old. 3 are gold and 3 black. One of the gold sex links looks different from the other two. Their feathers are coming in and all but this one has long tail feathers. She has a red tip on her beak. As a new chick she had brown tipped wings and the red beak. Now she is feathering out really dark compared to the other two. Can you tell sex by just those features?

Male red sex link chicks are yellow, not red so it is unlikely a sex link cockerel. It's possible another red breed got mixed in, like a New Hampshire, Rhode Island Red or production red. A picture would help.

Thank you. I will try and get a picture on soon.
