I agree, mine is still in the wait and see stage and like yours the comb got red/big fast. The other one is half the size no signs.Slow feathering isn't always a reliable indication. And hens will also have iridescent feathering - all of my black or black-laced hens and pullets do. The comb is what's making me go, "Hmmmm...." Not sure, though. A couple more weeks and you'll know.
ETA: Fairly certain GLW pullets sometimes have male-looking combs early on. Post pics again in 2 weeks.
I'm still holding out hope on my big girls as the comb has stayed the same and she seems to be growing into it.
