Cockerel or Pullet?

[PepsNick]

This is my 8-week old pullet, Amelia. She has been making some weird sounds lately and I've noticed that her comb is a tad big. Is "she" a rooster? Click the link for the pic. She has a large gobble too, for her age.

Those pictures are really too small to be able to say 100%, but it looks like a hen from what I can tell.

Thanks. If you find out anything more, tell me. This isn't the first time I've had chickens but am still fairly new. Especially with roo's! But if anyone else out there wants to help me out feel free!
