Not necessarily. Red sex links are created by red rooster to a silver hen - this ONLY works in the first generation. If you breed 2 red sex links together, they do not breed as sex links - you will not be able to tell sex by coloring. I have seen pictures of hen colored roosters in the 2nd generation.
Here's great information on sex links:

Heh... thanks... yeah, it looks like I accidentally left out a word... made me sound more sure than I was/am.
The part where I mentioned the sex linking...
"If they are the Red Star/Golden Comets, and they are all that lighter yellow color, then they would be cockerels because I they're sex linked."
Should have read:
"If they are the Red Star/Golden Comets, and they are all that lighter yellow color, then they would be cockerels because I think they're sex linked."
Silly iPad...
Still interested in seeing what they turn out to be.
