Hm, yeah then you'll have to wait and see. Pinkish comb and red wattles still points to cockerel to me, but I'd give it a couple more weeks and see if it gets any darker/more developed. My OEGB cockerel had a pinkish comb and wattles by ~5-6 weeks and coming up on 7 weeks it's starting to turn...
If their comb stays red and/or gets redder and the wattles start getting bigger, that's probably a cockerel. Anything turning red before 10 weeks has me sus.
