That's fairly red for 8 weeks....Can you get pictures of the saddle and hackle feathers? I don't know if the bird is old enough, but as the males get older they get shiny, long, pointy, and semi-translucent saddle and hackle feathers. That's a very accurate way to tell if the chick is a male...
How old is it? Without knowing the age of the bird, I'm leaning more towards pullet, because I don't see any male feathering and the comb isn't exceptionally big, but the face is pretty red, and that's what's making me sort of think there's a chance it could be a rooster.
