I have 2 SLW that are 12 weeks and they both look just like yours. I have assumed they are both females as well. One of mine is slightly red and the other is pretty light. I still think they are both hens though. I have a BLRW and I have assumed she is a hen as well. I think the wattles would be larger if they were roosters. My Barred Rock and RIR are very easy to tell and their wattles are much larger than those of the wyondotte 's.
