Updated photos taken tonight. Turned 12 weeks on Saturday. I can't see anything by way of saddles or hackles. This bird freaks any time it sees a phone so a lot of photos were white blurs. Comb/wattles have gotten bigger but not huge. More experience with keener eyes is appreciated. Still cockerel or fast growing pullet?
My 2 Langshan cockerels from the Ideal Dozen were slow to feather and late to develop, but definitely had large, if not bright, combs compared to their breed-sister.
