Even though she is light, she's shaped as a pullet should be. The comb and wattles would be larger if it were a cockerel. If that's a cockerel in sloooooooooooooo development, which is always possible, I'd be surprised. The head is also pullet shaped.
I am learning towards pullet as well, but her barring is further apart than her sisters and she is so red throughout the face that she has me confused.
