I am a *NOVICE*, but, I had white leghorns and I swear the combs were turning "reddish" IN THE FIRST WEEK!!!! And the combs/wattles grew at a ridiculously fast rate, AND they crowed VERY EARLY!! So if an exchequer's comb, etc., development is the same as for a white, I would definitely, definitely vote "PULLET".... !!!!!!!!!!!!!!
