Agreed, these all look like pullets so far. The older BCM I was on the fence with in the first photo (at 8 weeks) but with that little comb/wattle development in 2 weeks I think you're in the clear. They may just be fast maturing birds, plus single combed breeds often pink up early.
Ps, I absolutely adore your splash marans' little light colored eyebrows! So cute!
