How old is a buff orpington hen at it's full size?

[WildBilly]

i have a question, i have a buf orpington who lays eggs and i was wondering how many months until it fills out and it's comb grows?

my BUFF ORPINGTON is the gold one in this picture. today she is 6 months and 12 days old. She is BIG but i wonder when she reaches FULL size and COMB. ANYONE HAVE A YEAR OLD ORPINGTON who COULD ANSWER THIS?

Not all of them develop a bigger comb. In this photo she is over a year old. I also have a pullet who is nine months old who has filled out over the last couple of months.

Not all BO's get big combs. That may be as big as hers will get. I've had a few BO's before and some had super small combs and I had one who had such big wattles, she was often mistaken for a roo.
