what age can you tell what size a Serama is going to be?

[Nimueh Alene]

I have 9 Serama 3 pens with one cockerel and 2 hens each.. One set is 10 weeks old the other two are 8 weeks old. When will they be full grown? When can I safely put leg bands on .
I've posted pic on another thread trying to figure out what color pattern they are for their breeding card.

Most chickens aren't full grown until 6-12 months. Some continue to fill out until 2 years of age. I don't know about Serama, but I would assume they are like most bantams and they are grown at 5-8 months with some filling out for a few months after.
