pullet.
i have a bantam cockerel a week younger than your pullet and he was showing him comb and wattles at 4-5 months old. was crowing by that time too. was a late crower in my house.
could it be because of lack of enough light in the coop? i've moved mine into my garage coop so i could keep light on them longer in the evening and i've noticed a difference in my girls. one started laying this week-houdan/polish cross about 6mo, and the others are starting to show a lot more interest in the boxes since i keep ceramic eggs in them.
