Steve appears to have rounded feathers in the saddle and hackle area, like adult hens and like young chicks of both genders. Considering that Steve is 16 weeks old, that is a good indication of her being female.
The comb is getting larger and more red because she is nearly ready to lay eggs. Adult hens often have combs that are bright red and fairly large. Pullets keep their small pale combs for longer than young cockerels do, but by maturity both genders have bright red combs of varying sizes (all are bigger than young-chick combs, different breeds can have different size combs, and male combs do tend to be larger than female combs of the same breed.)
Spurs on hens are definitely possible. It is fairly common for hens to have small spurs, but rare for hens to have really long spurs like some roosters get.
So far, I think everything still points to Steve being a female.
. I don't remember where I read it but thought had read once in a great while a hen will have spurs also. I am so hoping Steve is a hen lol. But thinking that's not so. Thanks again for any input. 
). I'm so excited now. Thanks again!
